<title>Purpose</title>
<p>Drawing on social information processing theory and social comparison theory, we test how mentors&#x2019; daily ostracism triggers prot&#x00E9;g&#x00E9;s&#x2019; envy, thus leading to decreased in-role performance and increased displaced aggression.</p>
</sec>
<sec>
<title>Design/methodology/approach</title>
<p>Using an experience sampling study across three work weeks, the study provided theoretical and empirical examinations of dynamic, within-person processes related to mentors&#x2019; ostracism.</p>

<sec>
<title>Findings</title>
<p>Mentors&#x2019; daily ostracism triggers prot&#x00E9;g&#x00E9;s&#x2019; envy, which mediates the effect of mentors&#x2019; daily ostracism on prot&#x00E9;g&#x00E9;s&#x2019; displaced aggression and in-role performance. Our findings supported our hypothesis of the buffering effect of mentorship quality on the negative effect of mentors&#x2019; ostracism on prot&#x00E9;g&#x00E9;s&#x2019; envy but did not show a significant moderating effect on the mediating effect of prot&#x00E9;g&#x00E9;s&#x2019; emotions between mentors&#x2019; daily ostracism and prot&#x00E9;g&#x00E9;s&#x2019; behaviors.</p>

<title>Introduction</title>
<p>Ongoing ostracism is a painful and common experience (<xref ref-type="bibr" rid="ref28">Li et al., 2021b</xref>). Studies have explored general ostracism in the workplace that does not involve specific perpetrators (e.g., <xref ref-type="bibr" rid="ref17">Howard et al., 2020</xref>; <xref ref-type="bibr" rid="ref42">Wu et al., 2021</xref>) and particular types such as family ostracism (e.g., <xref ref-type="bibr" rid="ref44">Ye et al., 2021</xref>). However, the perpetration of ostracism by mentors in the workplace remains underexplored. Mentors play an important role for employees and are central to training and career development programs (<xref ref-type="bibr" rid="ref2">Allen et al., 2017</xref>). Prot&#x00E9;g&#x00E9;s typically choose respected superiors as their mentors (<xref ref-type="bibr" rid="ref43">Wu et al., 2019</xref>). Mentors may ostracize their prot&#x00E9;g&#x00E9;s as punishment, which increases their sense of dominance in social exchanges (<xref ref-type="bibr" rid="ref45">Zhong and Robinson, 2021</xref>), and the emotional and behavioral consequences can be devastating. Thus, we define mentors&#x2019; ostracism as the extent to which the prot&#x00E9;g&#x00E9;s perceive themselves to be excluded, rejected, or ignored by their mentors. Prot&#x00E9;g&#x00E9;s can be excluded from social connections with their mentors, such as being shut out of conversations or having their greetings ignored, or their mentors may avoid making eye contact with them (<xref ref-type="bibr" rid="ref10">Ferris et al., 2008</xref>).</p>
<p>However, this issue has received comparatively little research attention. Ostracism can be viewed as a kind of social death and can significantly influence individuals&#x2019; attitudes, well-being, and behavior (<xref ref-type="bibr" rid="ref28">Li et al., 2021b</xref>), so the lack of research into prot&#x00E9;g&#x00E9;s&#x2019; responses is surprising. Mentors may ostracize prot&#x00E9;g&#x00E9;s when they are having a bad day or are busy, or when their prot&#x00E9;g&#x00E9;s do not complete a critical assignment, but prot&#x00E9;g&#x00E9;s may simply perceive that ostracism occurs if they are sensitive to negative stimuli (<xref ref-type="bibr" rid="ref11">Ferris et al., 2016</xref>). Our research is therefore valuable, and we explore how prot&#x00E9;g&#x00E9;s encode and interpret mentors&#x2019; ostracism as unfavorable social comparison information and how they interact with their mentors, in terms of their emotional perceptions (i.e., envy), and the behavioral consequences (i.e., displaced aggression and in-role performance).</p>
<p>Social information processing theory provides a framework for our study (<xref ref-type="bibr" rid="ref34">Salancik and Pfeffer, 1978</xref>). Prot&#x00E9;g&#x00E9;s can rely on informational cues from mentors to confirm their cognitive and behavioral responses through social interactions, which result from information processing and are affected by social information. Displaced aggression can then be a consequence, and can occur when frustrated individuals cannot directly focus their anger on the source of frustration, or if they have no opportunity to do so (<xref ref-type="bibr" rid="ref29">Liu et al., 2015</xref>; <xref ref-type="bibr" rid="ref31">Poon et al., 2020</xref>). Mentors possess more resources and skills than their prot&#x00E9;g&#x00E9;s and are of higher status, so prot&#x00E9;g&#x00E9;s will aim to win their support (<xref ref-type="bibr" rid="ref14">Ghosh, 2014</xref>). Those frustrated by mentors&#x2019; daily ostracism may redirect their aggression toward innocent individuals. Ostracized prot&#x00E9;g&#x00E9;s are more likely to find themselves disadvantaged and may unwillingly have to regulate their aggressive impulses, which can lead to further aggressive behavior. Thus, mentors&#x2019; ostracism can trigger displaced aggression in their prot&#x00E9;g&#x00E9;s (<xref ref-type="bibr" rid="ref29">Liu et al., 2015</xref>). This displaced aggression then becomes a compensatory behavioral choice for prot&#x00E9;g&#x00E9;s in response to such ostracism. We also focus on in-role performance, defined as the effectiveness in successfully completing tasks and fulfilling responsibilities (<xref ref-type="bibr" rid="ref20">Kwan et al., 2022b</xref>). Mistreatment has been found to interfere with employee performance (<xref ref-type="bibr" rid="ref13">Foulk and Lanaj, 2021</xref>), and we hypothesize that ostracism may reduce in-role performance when prot&#x00E9;g&#x00E9;s attempt to change the negative condition of being ostracized by mentors. The need to process information in response to mistreatment can lead to this drop in performance (<xref ref-type="bibr" rid="ref26">Lemerise and Arsenio, 2000</xref>).</p>
<p>Envy has traditionally been explored from the perspectives of social comparison and social functioning (e.g., <xref ref-type="bibr" rid="ref18">Koopman et al., 2020</xref>), but no studies explore how mentors&#x2019; ostracism triggers prot&#x00E9;g&#x00E9;s&#x2019; envy in the social information process. Information that serves a social function can lead to emotional responses (<xref ref-type="bibr" rid="ref26">Lemerise and Arsenio, 2000</xref>). We combine the theories of social information processing and social comparison (<xref ref-type="bibr" rid="ref100">Festinger, 1954</xref>), and propose that prot&#x00E9;g&#x00E9;s&#x2019; envy has a mediating effect. Envy is an emotion that is often triggered through painful social comparison experiences and is associated with inferiority, hostility, and resentment (<xref ref-type="bibr" rid="ref35">Smith and Kim, 2007</xref>; <xref ref-type="bibr" rid="ref24">Lange et al., 2018</xref>; <xref ref-type="bibr" rid="ref27">Li et al., 2021a</xref>). Envy arises &#x201C;when a person lacks another&#x2019;s superior quality, achievement, or possession and either desires it or wishes that the other lacked it&#x201D; (<xref ref-type="bibr" rid="ref30">Parrott and Smith, 1993</xref>: 906). Ostracism by mentors can trigger unfavorable social comparisons and signals accompanying unfavorable information. Thus, we propose that mentors&#x2019; ostracism provides an aversive informational cue to prot&#x00E9;g&#x00E9;s and triggers more envy, and can include components such as frustration and pain (<xref ref-type="bibr" rid="ref24">Lange et al., 2018</xref>). Mentors&#x2019; ostracism is painful for prot&#x00E9;g&#x00E9;s because it represents a denial of their needs, leading to them feel inferior and resentful.</p>
<p>In terms of boundary conditions, mentorship quality determines how effective mentoring is, in terms of the benefits that prot&#x00E9;g&#x00E9;s gain from being mentored and their satisfaction with the relationship (<xref ref-type="bibr" rid="ref2">Allen et al., 2017</xref>). High-quality mentorship increases mutual trust and information exchange, which are important when processing and interpreting information, and reduces the likelihood that envy or workplace behaviors (i.e., in-role performance and displaced aggression) will emerge. Mentorship quality also influences how social information is interpreted. Based on social comparison theory, we suggest that good-quality mentorship provides opportunities to confirm information about social comparison processes (<xref ref-type="bibr" rid="ref15">Greenberg et al., 2007</xref>). Mentorship quality can then be considered a trade-off on the benefits and costs of dyadic relationship between mentors and prot&#x00E9;g&#x00E9;s, and if ostracism occurs on a daily basis, its effect on prot&#x00E9;g&#x00E9;s&#x2019; emotions will be moderated.</p>
<p>The paper makes several contributions to research into mentorship, ostracism, envy, aggression, and performance (see <xref rid="fig1" ref-type="fig">Figure 1</xref>). First, we assess prot&#x00E9;g&#x00E9;s who are ostracized by their mentors on a daily basis in terms of their processing of social information. We draw on the theories of social information processing and social comparison, and suggest that mentors&#x2019; ostracism is a signal of potentially unflattering or damaging social information, which influences how prot&#x00E9;g&#x00E9;s&#x2019; encode and interpret it. &#x201C;Daily experience sampling methods are ideal for capturing processes that change quickly&#x201D; (<xref ref-type="bibr" rid="ref2">Allen et al., 2017</xref>, p. 332), in addition to informing a detailed understanding of the interpersonal dynamics in the mentoring relationship. We thus provide novel evidence in the mentoring literature (<xref ref-type="bibr" rid="ref23">Lanaj and Jennings, 2020</xref>). Second, ours is the first study to empirically investigate whether mentors&#x2019; daily ostracism can lead to envy and negative behavior in prot&#x00E9;g&#x00E9;s (i.e., reduced in-role performance and displaced aggression) using a within-person approach. We extend the literature by revealing the complex emotional state that can lead to envy after social information is received (<xref ref-type="bibr" rid="ref7">Duffy et al., 2021</xref>; <xref ref-type="bibr" rid="ref27">Li et al., 2021a</xref>). Third, we consider mentorship quality when examining the direct effects of ostracism on prot&#x00E9;g&#x00E9;s and its indirect effects on their behavior <italic>via</italic> their envy. Thus, we contribute to the mentorship literature by demonstrating that the emotional and behavioral consequences of ostracism do not occur in a vacuum, but are affected by the mentor&#x2013;prot&#x00E9;g&#x00E9; relationship, thus highlighting the importance of mentorship quality. We examine the daily effects of mentors&#x2019; ostracism on the emotional and behavioral responses of their prot&#x00E9;g&#x00E9;s when processing social information.</p>

<title>Hypothesis development</title>
<p>Social information processing theory emphasizes that social information is affected by the context and consequences of past choices, in which behavior is considered in terms of what others think (<xref ref-type="bibr" rid="ref34">Salancik and Pfeffer, 1978</xref>). Social information processing involves five steps that occur in response to a social situation cue before a behavioral response is made: encoding (e.g., figuring out what happened); interpretation/representation (e.g., questioning why it happened&#x2014;by accident or deliberately); a response search (e.g., evaluating the situation); a response decision (e.g., balancing the benefits and costs); and enactment following the accepted model of social behavior (<xref ref-type="bibr" rid="ref3">Crick and Dodge, 1994</xref>).</p>
<p>Ostracism can be regarded as nonverbal information and can occur if a mentor does not engage with a prot&#x00E9;g&#x00E9; when it is socially appropriate to do so. Prot&#x00E9;g&#x00E9;s may then perceive this as negative social information, which can lead to painful emotions and destructive behaviors.</p>
<sec id="sec3">
<title>Mentors&#x2019; ostracism, prot&#x00E9;g&#x00E9;s&#x2019; envy, displaced aggression, and in-role performance</title>
<p>Unfavorable social comparison information can lead individuals to consider what they lack relative to superior others (<xref ref-type="bibr" rid="ref8">Duffy et al., 2012</xref>). Envy is a painful form of upward social comparison, and avoiding pain is a fundamental human drive (<xref ref-type="bibr" rid="ref36">Tai et al., 2012</xref>). If prot&#x00E9;g&#x00E9;s are hurt by the ostracism of their mentors they can become envious, as this unfavorable social comparison information focuses the attention of prot&#x00E9;g&#x00E9;s on the discrepancy between mentors&#x2019; superiority and their own inferiority. Ostracism can occur even if from the mentors&#x2019; perspective there is no malicious intention, as it can still threaten prot&#x00E9;g&#x00E9;s&#x2019; sense of control (<xref ref-type="bibr" rid="ref41">Williams, 2009</xref>), and the emotion of envy can then emerge (<xref ref-type="bibr" rid="ref4">Crusius et al., 2020</xref>). Mentors&#x2019; ostracism can influence prot&#x00E9;g&#x00E9;s&#x2019; perceptions of a situation and how they attribute meaning to it (<xref ref-type="bibr" rid="ref26">Lemerise and Arsenio, 2000</xref>), thus increasing their awareness of discrepancies in mentoring. As a form of interpersonal mistreatment, ostracism can replace respect and propriety in dyadic communications. Prot&#x00E9;g&#x00E9;s perceive mentors&#x2019; ostracism as signaling a discrepancy between their actual state and their expectations of support, leaving them open to negative emotions and feelings of envy. As an input in the processing of social information, ostracism can be a stimulus that individuals become sensitive to (<xref ref-type="bibr" rid="ref150">Yang and Treadway, 2018</xref>). Prot&#x00E9;g&#x00E9;s then perceive the mistreatment that they are subject to and will be aware of the discrepancy, leading to increased envy (<xref ref-type="bibr" rid="ref18">Koopman et al., 2020</xref>).</p>
<p>In terms of social information processing theory, ostracized prot&#x00E9;g&#x00E9;s can be viewed as experiencing a lack of resources and information, because their mentors are more experienced and have more advantages in the workplace. They can then experience losses of career-related and psychosocial support from their mentors (<xref ref-type="bibr" rid="ref2">Allen et al., 2017</xref>), which can trigger resentment and inferiority and consequently increase the feeling of envy (<xref ref-type="bibr" rid="ref35">Smith and Kim, 2007</xref>). Ostracized prot&#x00E9;g&#x00E9;s may be hurt by their mentors&#x2019; silence and are likely to experience negative emotions (<xref ref-type="bibr" rid="ref11">Ferris et al., 2016</xref>) that can include envy. In social terms, ostracism suggests the denial of prot&#x00E9;g&#x00E9;s&#x2019; needs, implying that it hinders access to information. Such information may signal better strategies for success, and if individuals lack information that is useful for gaining advantages, they are likely to experience envy (<xref ref-type="bibr" rid="ref18">Koopman et al., 2020</xref>). Mentors&#x2019; daily ostracism is ongoing, dynamic, and time-dependent, and varies for the fluctuating situational factors on a daily basis. Thus, we propose the following:</p>
<disp-quote>
<p><italic>Hypothesis 1</italic>: Mentors&#x2019; daily ostracism is positively related to prot&#x00E9;g&#x00E9;s&#x2019; envy.</p>
</disp-quote>
<p>Envy is a self-referential emotion that can emerge through upward social comparisons (<xref ref-type="bibr" rid="ref4">Crusius et al., 2020</xref>). Ostracized prot&#x00E9;g&#x00E9;s may feel that they do not deserve their mentors&#x2019; support, and can lose their sense of control when encoding and reasoning their mentors&#x2019; ostracism through nonverbal social information processing. They may then be motivated to assert their superiority by being aggressive toward inferiors (i.e., engaging in displaced aggression) or disengaging from their work, thus decreasing their in-role performance. Envy is a painful emotion accompanied by other negative affective components, such as a sense of inferiority and frustration (<xref ref-type="bibr" rid="ref24">Lange et al., 2018</xref>). The frustration&#x2013;aggression hypothesis suggests that frustration may impel an individual to vent their aggression on others (<xref ref-type="bibr" rid="ref31">Poon et al., 2020</xref>). Prot&#x00E9;g&#x00E9;s who are ostracized by their mentors may then release their negative emotions by being aggressive toward innocent colleagues.</p>
<p>Displaced aggression is a form of behavior associated with negative emotions (e.g., <xref ref-type="bibr" rid="ref29">Liu et al., 2015</xref>). Prot&#x00E9;g&#x00E9;s who exhibit displaced aggression may be seeking to fulfill their psychological needs, through effectively interacting with the environment and compensating for their perceived lack of competence. Envy in prot&#x00E9;g&#x00E9;s can be provoked by their mentors&#x2019; ostracism, but as they are prevented from retaliating against the source of the provocation (their mentors) they may subsequently be aggressive toward innocent targets. This lack of a direct focus can then lead to displaced aggression, which can satisfy their psychological needs. Prot&#x00E9;g&#x00E9;s suppress their impulse for revenge against their mentors because they require a mutual and reciprocal relationship and expect long-term mentoring support. Thus, envious prot&#x00E9;g&#x00E9;s reason on and interpret the information that lies behind their mentors&#x2019; ostracism and balance the cost of targeting innocent others, leading to displaced aggression.</p>
<p>In-role performance is the effective performance of formally prescribed job responsibilities (<xref ref-type="bibr" rid="ref19">Kwan et al., 2022a</xref>). Mentors&#x2019; ostracism induces a negative psychological state in prot&#x00E9;g&#x00E9;s, which makes them feel inferior and less confident at work, thus reducing their in-role performance (<xref ref-type="bibr" rid="ref27">Li et al., 2021a</xref>). According to social information processing theory, envy is present within an individual&#x2019;s impulsive system. Thus, it can be a response to mentors&#x2019; ostracism when encoding information and can emerge in the negative emotional state resulting from being ostracized, which triggers displaced aggression and reduces in-role performance. Thus, we propose the following:</p>
<disp-quote>
<p><italic>Hypothesis 2</italic>: Prot&#x00E9;g&#x00E9;s&#x2019; envy mediates the positive relationship between mentors&#x2019; daily ostracism and prot&#x00E9;g&#x00E9;s&#x2019; displaced aggression.</p>
<p><italic>Hypothesis 3</italic>: Prot&#x00E9;g&#x00E9;s&#x2019; envy mediates the negative relationship between mentors&#x2019; daily ostracism and prot&#x00E9;g&#x00E9;s&#x2019; in-role performance.</p>
</disp-quote>

<title>The cross-level moderating effect of mentorship quality</title>
<p>Mentorship quality is defined in social information processing theory as &#x201C;an overall evaluation of the mutual benefit of and satisfaction with the relationship&#x201D; (<xref ref-type="bibr" rid="ref19">Kwan et al., 2022a</xref>, p. 350), and can thus alleviate the effect of ostracism on prot&#x00E9;g&#x00E9;s&#x2019; envy through three channels. First, high-quality mentorship increases the access that prot&#x00E9;g&#x00E9;s have to social information by maintaining a positive and significant interpersonal relationship with their mentors (<xref ref-type="bibr" rid="ref150">Yang and Treadway, 2018</xref>). To maintain high-quality mentorship, ostracized prot&#x00E9;g&#x00E9;s suppress their negative emotions and actions. In contrast, low-quality mentorship makes prot&#x00E9;g&#x00E9;s more susceptible to ostracism and in turn more likely to be envious. Second, prot&#x00E9;g&#x00E9;s who receive high-quality mentorship have a mutually respectful, trusting, and loyal relationship with their mentors. A positive and healthy workplace environment can buffer the destructive effect of ostracism on prot&#x00E9;g&#x00E9;s&#x2019; emotional and behavioral responses. Third, high-quality mentorship enables prot&#x00E9;g&#x00E9;s to proactively acquire social information, such as the performance pressure or anxiety felt by their mentors, leading to increased understanding and tolerance of any ostracism. The high quality of the mentorship leads them to seek excuses for the ostracism and suppress their envy, mitigating the negative consequences of the resulting discrepancy (<xref ref-type="bibr" rid="ref18">Koopman et al., 2020</xref>). Thus, we propose the following:</p>
<disp-quote>
<p><italic>Hypothesis 4</italic>: The relationship between mentors&#x2019; daily ostracism and prot&#x00E9;g&#x00E9;s&#x2019; envy is stronger when mentorship quality is low (vs. high).</p>
</disp-quote>
<p>The buffering effect of mentorship quality on the relationship between mentors&#x2019; ostracism and prot&#x00E9;g&#x00E9;s&#x2019; envy can emerge, and can further trigger increased displaced aggression and decreased in-role performance. Drawing on <xref ref-type="bibr" rid="ref9">Edwards and Lambert&#x2019;s (2007)</xref> moderated mediation procedure and the theoretical arguments presented in Hypotheses 1&#x2013;4 we build a moderated mediation model with the following hypotheses:</p>

<title>Methods</title>
<sec id="sec6">
<title>Participants and procedures</title>
<p>To test our model, we conducted a study using an experience sampling methodology (ESM) as recommended by <xref ref-type="bibr" rid="ref12">Fisher and To (2012)</xref>, that provided theoretical and empirical examinations of dynamic, within-person processes related to mentors&#x2019; ostracism. The data were collected in an electronics factory located in Xiamen, Fujian Province, China. Four assistants helped us to collect daily data and 70 frontline workers initially took part in our survey. They worked with their mentors almost every day and most of them had been with the company for less than 2 years, and thus they needed their mentors&#x2019; help to ensure that their productivity was satisfactory. All of the participants were assured that their information would be kept confidential. They were surveyed 3 times daily on 10 consecutive workdays, and were informed that rewards would be given randomly every day and that they would earn up to 100 yuan after they completed the daily surveys.</p>
<p>The survey took place over 3 weeks. In the first week, we collected demographic information and mentorship quality data from the 70 frontline workers. The daily portion of the study was conducted for 10 consecutive workdays over the following 2 weeks. The study involved three surveys per day: the first in the morning (7:00 a.m. to 9:00 a.m.); the second in the afternoon (3:00 p.m. to 5:00 p.m.); and the third in the evening after they left work (7:00 p.m. to 9:00 p.m.). The morning survey assessed mentor ostracism, and the control variables were positive and negative affect. The afternoon survey assessed prot&#x00E9;g&#x00E9;s&#x2019; envy. The evening survey assessed in-role performance and displaced aggression. Of the 70 prot&#x00E9;g&#x00E9;s who opted in, 55 completed the survey for at least 3 full days (i.e., morning, afternoon, and evening surveys), and thus comprised the final sample (78.57% retained). Most participants were male (60.0%), and more than 90% had a bachelor&#x2019;s degree or higher.</p>

<title>Control variables</title>
<p>We considered several control variables. First, we controlled positive affect and negative affect, as measured with a scale developed by <xref ref-type="bibr" rid="ref39">Watson et al.

Cronbach&#x2019;s alpha was 0.96 for both positive and negative affect. Second, we controlled gender, which was coded as 1 for male and 2 for female. A meta-analytic review revealed that gender is significantly related to ostracism, and that males report more ostracism (<xref ref-type="bibr" rid="ref17">Howard et al., 2020</xref>).</p>

<sec id="sec15">
<title>Analytic approach</title>
<p>Given the multilevel structure of our data (days and people), we applied multilevel path analysis in Mplus 7.4 to test the hypothesized relationships. First, we verified that there was sufficient within-individual variability to justify a multilevel analysis, as the percentages of total variance ranged from 0.26 to 0.48 (e.g., <xref ref-type="bibr" rid="ref140">Podsakoff et al., 2019</xref>; <xref ref-type="bibr" rid="ref33">Puranik et al., 2019</xref>). We then proceeded to conduct a multilevel path analysis, and simultaneously modeled all of the variables in <xref rid="fig1" ref-type="fig">Figure 1</xref>.</p>
<p>Second, we centered the predictors both within and between individuals. The within-individual predictors were group-mean centered, and the between-individual predictors grand-mean centered (e.g., <xref ref-type="bibr" rid="ref22">Lanaj et al., 2021</xref>), which enabled us to study within-individual relationships by controlling for between-individual confounders (<xref ref-type="bibr" rid="ref6">Dimotakis et al., 2011</xref>). All of the within-individual relationships were modeled as random slopes and control variables with fixed slopes to reduce model complexity (e.g., <xref ref-type="bibr" rid="ref22">Lanaj et al., 2021</xref>). To test the moderation effect, we centered mentorship quality by the grand mean and calculated the product of mentors&#x2019; ostracism and mentorship quality.</p>
<p>Third, we tested the indirect effects and used a bootstrap procedure with 20,000 iterations to estimate the bias-corrected confidence intervals (CIs) for each indirect effect based on the Monte Carlo method, to assess the mediation effect (<xref ref-type="bibr" rid="ref32">Preacher and Selig, 2012</xref>). Finally, to confirm our hypothesized conditional indirect effect of mentor ostracism on prot&#x00E9;g&#x00E9;s&#x2019; daily displaced aggression <italic>via</italic> their emotions (i.e., envy and being envied), we checked the significance of the difference in this indirect effect at higher and lower levels of mentorship quality (+/&#x2212; SD; <xref ref-type="bibr" rid="ref16">Hayes, 2015</xref>).</p>

<p>We examined whether mentorship quality, as a between-level variable, would moderate the within-individual direct effect of mentors&#x2019; ostracism and prot&#x00E9;g&#x00E9;s&#x2019; emotions, and the indirect effect of ostracism on prot&#x00E9;g&#x00E9; behavior through their emotions.

<p>The indirect effect of mentors&#x2019; ostracism on daily displaced aggression <italic>via</italic> prot&#x00E9;g&#x00E9;s&#x2019; envy was significant at higher levels of mentorship quality (estimate: 0.022; 95% CI [0.0069, 0.0659]) and at lower levels (estimate: 0.039; 95% [0.0068, 0.0653]), which indicated no significant difference in the indirect effect (estimate: -0.017; 95% CI [&#x2212;0.0710, 0.0098]).

<title>Discussion</title>
<sec id="sec18">
<title>Theoretical implications</title>
<p>In this study, we focused on the victims of ostracism from mentors and empirically explored how this ostracism affects the envy and behavior of their prot&#x00E9;g&#x00E9;s from their perspective. First, the effect of ostracism from mentors is underexplored, and ours is the first study to extend mentoring literature by applying a daily experience sampling method in researching its emotional and behavioral consequences within mentoring context, that responds the call for exploring emotional reaction to ostracism (<xref ref-type="bibr" rid="ref38">Wang and Li, 2022</xref>). We draw on the theories of social information processing and social comparison, and focus on a specific type of workplace ostracism. We contribute to the conventional assumption that mentors are the perpetrators (<xref ref-type="bibr" rid="ref17">Howard et al., 2020</xref>) by extending the research beyond supervisor ostracism (e.g., <xref ref-type="bibr" rid="ref21">Kwan et al., 2018</xref>) and family ostracism (e.g., <xref ref-type="bibr" rid="ref44">Ye et al., 2021</xref>) to the consequences of daily ostracism from mentors.</p>
<p>Second, we contribute to research into envy in the workplace by exploring the mediating mechanism of prot&#x00E9;g&#x00E9;s&#x2019; envy by considering the meta-analytical review on empirical research of envy (<xref ref-type="bibr" rid="ref27">Li et al., 2021a</xref>), which underlies the effect of mentors&#x2019; daily ostracism on prot&#x00E9;g&#x00E9;s&#x2019; displaced aggression and in-role performance. Based on social information processing theory, this finding provides the first empirical support for the effect of envy on the relationship between mentors&#x2019; ostracism and their prot&#x00E9;g&#x00E9;s&#x2019; behavior. Thus, we inform the understanding of how negative emotions (e.g., envy) are involved in the social information processing framework, leading to deviant behaviors in the workplace.</p>
<p>Third, we found that mentorship quality moderates the relationship between mentors&#x2019; daily ostracism and prot&#x00E9;g&#x00E9;s&#x2019; envy, and has a stronger positive relationship for prot&#x00E9;g&#x00E9;s experiencing lower-rather than higher-quality mentorship. These findings are consistent with research suggesting that the quality of leader&#x2013;member exchange influences the emotion of envy (e.g., <xref ref-type="bibr" rid="ref37">Vecchio, 2005</xref>; <xref ref-type="bibr" rid="ref27">Li et al., 2021a</xref>). However, we did not find that mentorship quality moderates the indirect effect of mentors&#x2019; daily ostracism on prot&#x00E9;g&#x00E9; behavior through their envy. Other mediating factors may be moderated by mentorship quality, and further research should assess these when examining the relationships among mentorship quality, ostracism from mentors, and their prot&#x00E9;g&#x00E9;s&#x2019; behavior.</p>
</sec>
<sec id="sec19">
<title>Practical implications</title>
<p>Our finding that mentors&#x2019; daily ostracism has a negative effect on prot&#x00E9;g&#x00E9;s&#x2019; envy and behavior (i.e., displaced aggression and in-role performance) has various implications. First, organizations should provide training programs for mentors and prot&#x00E9;g&#x00E9;s to help them to build healthy and positive mentoring relationships (<xref ref-type="bibr" rid="ref120">Hu et al., 2021</xref>), and should not condone the use of ostracism as a punishment. Mentors should keep in mind that ostracizing their prot&#x00E9;g&#x00E9;s may negatively affect them and they should instead ensure that communication with their prot&#x00E9;g&#x00E9;s is effective.</p>
<p>Second, envy is a negative emotion that can lead to undesirable behavior in the workplace and in life in general. Prot&#x00E9;g&#x00E9;s should learn how to regulate their negative emotions rather than be consumed by them (<xref ref-type="bibr" rid="ref25">Lee et al., 2018</xref>). Our research reveals that mentors&#x2019; daily ostracism is highly likely to lead to envy in their prot&#x00E9;g&#x00E9;s, so mentors should aim to alleviate such negative emotions by refraining from ostracizing their prot&#x00E9;g&#x00E9;s. In addition, by ignoring such ostracism, prot&#x00E9;g&#x00E9;s can focus more on their own performance at work. Various emotion regulation approaches can be taken to address feelings of envy, such as situation modification, attentional deployment, cognitive change, and response modulation.</p>
<p>Third, as we found that mentorship quality has a significant role in terms of ostracism and envy, organizations should attempt to improve the quality of mentorship (Hu et al., 2021) to alleviate any envious feelings held by prot&#x00E9;g&#x00E9;s. Transactional or socio-emotional viewpoints suggest that mentorship quality depends on both parties and requires effort from mentors and prot&#x00E9;g&#x00E9;s.</p>

<title>Limitations and directions for future research</title>
<p>This study has several limitations and potential directions for future research. First, our data were collected from the same source, leading to concerns about common method variance. Thus, our theoretical model can be tested using other sources, such as measuring ostracism from the perspective of mentors and displaced aggression from those of family members.</p>
<p>Second, our measure of ostracism may not be fully generalizable. We selected frontline workers in an electronics factory as our sample to ensure that mentors and prot&#x00E9;g&#x00E9;s interacted on a daily basis and that there was variance in their daily behavior. Whether our findings can be generalized to other types of organizations (e.g., frontline employees in hospitality businesses) should be explored. Further research can thus be based on samples from various companies and industries. In terms of causal inference, we regarded ostracism that occurs in the morning as one broad interaction unit, but mentor&#x2013;prot&#x00E9;g&#x00E9; dyads may experience various interactions with distinct levels of ostracism. Future research can apply an episodic design to capture the dynamics of mentors&#x2019; ostracism.</p>
<p>Third, we only consider envy as the emotional mechanism, while other emotions may be involved. For example, ostracized prot&#x00E9;g&#x00E9;s may feel anger or anxiety toward their mentors. Further research into the emotional reactions that result from mentors&#x2019; ostracism would be of benefit.</p>
<p>Fourth, we did not collect any data to capture the quality of the relationships between mentors and prot&#x00E9;g&#x00E9;s on a daily basis. Future research should consider relationship quality and other control variables.</p>
<p>Finally, our study&#x2019;s sample size was small, and was limited to a single factory. We suggest that other research teams can extend our research by applying the theoretical model and the daily experience sampling method, which reflects variability on a daily basis, to better understand the effects of ostracism.</p>

<title>Conclusion</title>
<p>Based on social information processing theory, we introduce a dynamic theoretical framework that extends mentoring literature by integrating theories of ostracism, envy, in-role performance, and displaced aggression as daily constructs. The study shows mentors&#x2019; daily ostracism triggers prot&#x00E9;g&#x00E9;s&#x2019; envy, and subsequently leading to decreased in-role performance and increased displaced aggression. The study also shows that mentorship quality can lessen the effect of mentorship quality on prot&#x00E9;g&#x00E9;s&#x2019; envy. We hope that this study will open the door for more research on employees&#x2019; behaviors and emotions at work on a day-to-day basis.</p>
