Supervisors’ relational transparency moderates effects among employees’ illegitimate tasks and job dissatisfaction: a four-wave panel study

Despite repeated calls for the inclusion of leadership in research on illegitimate tasks, little is known about what supervisors can actually do to mitigate negative effects of illegitimate tasks. We propose transparent leadership behavior as an effective means that buffers detrimental effects of illegitimate tasks. We further propose reciprocal effects between illegitimate tasks and job dissatisfaction. Based on a short panel study with four surveys across four consecutive weeks, data of 347 employees were analyzed using multiple group structural equation models. For the two facets of illegitimate tasks, results were more consistent for unnecessary than for unreasonable tasks. We found main and moderating effects in both the normal causal and the reversed causal direction for unnecessary tasks, with more consistent main effects in the reversed direction and stronger moderating effects in the normal direction: Job dissatisfaction rather led to unnecessary tasks than vice versa; while high transparency particularly buffered the effects of unnecessary tasks on job dissatisfaction. Thus, by means of transparent leadership behavior, supervisors are able to effectively intervene in the vicious circle between illegitimate tasks and employees' job dissatisfaction and thereby benefit working conditions for leaders and followers alike.
