A recent study examined the complex relationship between workaholism and job performance.
Drawing on achievement motivation theory, it shows that workaholism is positively related to performance via work engagement, so that workaholism is positively related to work engagement, which in turn is positively related to performance. Based on the work, non-work, and sleep model, it also shows that workaholism is negatively related to performance via poor sleep quality, so that workaholism is positively related to poor sleep quality, which in turn is negatively related to performance. The positive indirect effect of workaholism on performance was larger than the negative one. Although workaholic employees tended to perform better, they also reported poorer sleep quality, which may be detrimental for their wellbeing.
