Abstract

Purpose

Not much is known about the conditions under which the negative relationship between co-worker undermining and employee outcomes may wax or wane. This study seeks to address this issue by analysing the role of leadership in mitigating the negative impact of co-worker undermining on employee outcomes. Drawing on expectancy violation theory (EVT), the study proposes that servant leadership will alleviate the association between co-worker undermining, emotional exhaustion and consequently organisational commitment.

Design/methodology/approach

Two-wave time-lagged data were collected from a sample of 345 nurses working under 33 supervisors in a large public hospital in Malaysia. To account for the nested nature of the data, generalised multilevel structural equation modeling (GSEM) in STATA was used to test the hypotheses.

Findings

After controlling for transformational leadership, co-worker undermining was indirectly related to organisational commitment via emotional exhaustion, and this indirect relationship was weaker when servant leadership was high.

Practical implications

Organisations need to invest in interventions that help reduce co-worker undermining and put emphasis on promoting servant leadership.

Originality/value

The study extends the literature by introducing EVT as a new theoretical lens to analyse the consequences of co-worker undermining on employee outcomes. The study also addresses calls for research on the role of leadership in ameliorating the negative consequences of co-worker undermining.
