In other words, does optimism mitigate or exacerbate the experience of workplace injustice? This is an important practical question because optimism is a promising avenue for interventions. Taking an affective events perspective, we expect that daily events of peer injustice trigger affective reactions, and that the degree of trait optimism will influence the strength of these affective reactions. Thus, we develop two competing predictions. The reverse buffer hypothesis, which suggests that optimists’ heightened expectations lead to increased disappointment and hence more negative emotions in the face of injustice, and the buffer hypothesis, which suggests that optimists’ better use of coping strategies allows them to experience less negative emotions. In a 10-day diary study with 251 employees, we find support for the buffer hypothesis of optimism on peer injustice experiences: those higher in optimism reported fewer negative emotions and lower levels of sleep problems the night following such experiences. Our findings illustrate how cognitive and emotional mechanisms interact in predicting reactions to injustice, particularly sleep problems. date: 2023-09-05 date_type: published publisher: Sage publishing id_number: 10.1177/10596011231200550 faculty: gestion divisions: CRM keywords: peer justice, dispositional optimism, sleep, affective events language: en has_fulltext: FALSE doi: 10.1177/10596011231200550 view_date_year: 2023 full_text_status: none publication: Group and Organization Management refereed: TRUE issn: 1059-6011 oai_identifier: oai:tsm.fr:2875 harvester_local_overwrite: issn harvester_local_overwrite: pending harvester_local_overwrite: creators_idrefppn harvester_local_overwrite: creators_halaffid harvester_local_overwrite: publisher harvester_local_overwrite: creators_id harvester_local_overwrite: title harvester_local_overwrite: date harvester_local_overwrite: hal_id harvester_local_overwrite: hal_version harvester_local_overwrite: hal_url harvester_local_overwrite: hal_passwd oai_lastmod: 2024-03-07T09:16:17Z oai_set: tsm site: ut1 hal_id: hal-04508757 hal_passwd: gjlafbuf hal_version: 1 hal_url: https://hal.science/hal-04508757 citation: Ohana, Mark and Fortin, Marion (2023) Half Just or Half Unjust ? the Influence of Dispositional Optimism on the Link Between Interpersonal Peer Injustice, Negative Emotions and Sleep Problems.
