Background: The effort-reward imbalance at work model offers a theoretical and analytical framework to estimate the subjective perception of work-related stress. High demands and low rewards in return can harm mental and physical health, well-being, and life satisfaction. According to the theory, overcommitment partially explains why employees endure such straining jobs. In Germany, cultural and economic aspects of labor differ between East and West. Incomes are lower in the East, while work centrality there is higher. In this article, the effects of effort-reward imbalance, overcommitment, and income on life satisfaction as well as their interactions with region were analyzed to gain a clearer picture of regional disparities regarding life satisfaction and the generality of this work stress model in Germany.

Methods: Data from 3848 participants from 2006 to 2011 of the German Socio-Economic Panel were analyzed. Within-between models were estimated, including fixed and random effects of the continuous form of effort-reward imbalance to predict subjective life satisfaction. Time-variant covariates – e.g., overcommitment or income – as well as time-constant variables – e.g., region, sex, education – were integrated. Differences in regional labor markets between East and West Germany were considered.

Results: Easterners exhibited higher imbalances and overcommitment than Westerners, indicating worse working conditions. Higher imbalances and overcommitment were associated with lower life satisfaction within and between participants, whereas for income only random effects were supported. While region did not moderate the effect of work stress, East Germans’ life satisfaction benefitted more from a higher income.

Conclusion: The importance of internal work structures in terms of recognition, adequate pay, advancement opportunities, or time pressure were underlined. As compared to the West, Easterners’ life satisfaction benefitted more from higher income but not more from a lower imbalance or lower overcommitment. The interplay between materialistic and nonmaterialistic rewards at work should be focused on in the future.
