Coworker support as a moderator in the relationship between daily experience of workload and an individual's experience of same-day WFC: a buffer or an intensifier? By: Trottier, Mélanie; Bentein, Kathleen. Community, Work & Family. Dec2019, Vol. 22 Issue 5, p569-588. 20p.

The present study looks at the interaction between daily experiences in the workplace – daily workload and daily coworker support – and examines its influence on negative affect and its subsequent impact on same-day work–family conflict (WFC). It proposes two competing moderation hypotheses (buffering vs. intensifying). According to the COR theory, support received from coworkers represents a resource that should buffer the relationship between daily workload and same-day WFC, because it should prevent individuals from experiencing negative affect triggered by high workload episodes which represents a threatening or stressful situation. In contrast, the threat to self-esteem model posits that receiving social support may engender feelings of indebtedness or helplessness at the time such support is provided, thereby amplifying the impact of workload experience on same-day WFC via an increased negative affect. Data collected from 130 pharmacists over 5 consecutive days were analyzed through multilevel structural equation modeling. The results support the hypothesis of the intensifying conditional indirect effect, and show that when individuals are provided with coworker support while experiencing high workload, negative affect is aggravated and hence, in turn, same-day WFC increases. This challenges the mainstream hypothesis that views social support as an important resource in protecting people from stressful events.
