This article reports a systematic review of findings on the long-term development of employee well-being (i.e. burnout, engagement, and job satisfaction), taking into account the effects of time lag, age, and job change. The systematic analysis of the 40 selected studies revealed that the level of employee well-being was generally high but not fixed – instead changes in mean levels over time were typical. In addition, the stability of well-being was found to be relatively low, as the explained variances were below 50%. Age and change of job were the major factors influencing stability: younger employees and job changers tended to display larger across time changes. The findings of this review suggest that the indicators of employee well-being can meaningfully be applied in future research in measuring changes in employees’ well-being (read more).
