Families have been hit hard by the COVID-19 pandemic and its associated lockdown, but barely any research has been conducted yet, investigating how COVID-19-related stressorsand, specifically, disruptions in established employment arrangementsaffected couples' relationship quality. To account more comprehensively for such non-monetary costs of the COVID-19 pandemic, the present study investigates whether changes in partners' employment situation during the COVID-19 crisisparticularly home-office and short-time workhad an immediate impact on the relationship satisfaction of cohabiting married and unmarried couples. To do so, we estimated fixed-effects regression models, exploiting unique data from the German Family Panel (pairfam; wave 11) and its supplementary COVID-19 web-survey. We observed a substantial proportion of respondents experiencing positive (20%) or negative (40%) changes in relationship satisfaction during the crisis. Relationship satisfaction has decreased, on average, for men and women alike, almost irrespective of whether they experienced COVID-19-related changes in their employment situation. While partners' employment situation hardly moderated the negative association between respondents' employment and relationship satisfaction, the presence of children seemed to buffer partly against a COVID-19-related decrease. Our results thus confirm previous findings suggesting that the COVID-19 pandemic constitutes a threat to couples' relationship quality and healthy family functioning more generally.
