This time-lagged study, using the framework of the JD-R model, tested the mediating role of job crafting measuring: at T1, work engagement, workaholism and emotional exhaustion; at T2, job crafting; and, at T3, flourishing, job performance and job satisfaction. Respondents were 443 Spanish employees working in different companies. Results show that job crafting mediates the relationship between work engagement and some of its outcomes (job performance and flourishing). In particular, the job crafting component 'increasing structural job resources' mediates the positive effect of work engagement on flourishing and job performance, and the job crafting component 'increasing challenging demands' mediates the positive effect of work engagement on job performance. No job crafting mediation is found between work engagement and job satisfaction.
Keywords: job crafting; job demands; job performance; job resources; wellbeing; work engagement.
