Drawing on the social identity literature, this study offers theoretical arguments and empirical evidence to understand reactions to divergent perceptions of organizational external prestige (PEP) and organizational support (POS) -two crucial bases of employees' social worth. Across three studies, using both experimental and field data, we find that PEP-POS discrepancy contributes to employees' perceptions of organizational cynicism and silence behaviour, especially when PEP is high and POS is low (rather than the reverse). Consistent with our social identity perspective, we find that ambivalent identification, that is, the simultaneous identification and disidentification of an individual with an organization, is a key mediating mechanism that transfers the interactive relationship of PEP and POS to cynicism and silence. These findings contribute to a more comprehensive understanding of the dynamics of individuals' social worth at work.

International audienceThe physical health consequences of perceived injustice at work are an important yet underexplored area of research. Using the job-stress recovery literature as an overarching framework, we argued that incomplete recovery because of sleep disorders and subsequent emotional exhaustion is a possible underlying mechanism through which organizational justice relates to employee musculoskeletal disorders (MSD). Using both self-administered questionnaires and medical examination to assess MSD, we tested our argument in two studies. Based on a randomly selected sample of employees from a variety of organizations, Study 1 found organizational justice to be negatively related to MSD through diminished sleep-related disorders. Using a sample of employees in nursing homes for the elderly, Study 2 extended these results by showing that the organizational justice–MSD relationship is sequentially mediated by sleep disorders and emotional exhaustion
