Many European families are affected by the 24/7 economy, but relatively little is known about how working parents experience nonstandard hours. The aim of this study was to analyze the possible associations of dual earners’ work schedules and other work-related factors with their experience of time- and strain-based work–family conflict. These phenomena were examined among dual earners living in Finland, the Netherlands, and the United Kingdom, countries that differ in working time practices and policies. Multigroup structural equation modeling was used to analyze cross-cultural data on dual earners with children aged 0 to 12 years (N = 1,000). The results showed that working nonstandard schedules was associated with increased time-based work–family conflict, but only among Finnish and British parents. Poorer financial situation, working longer hours, more time spent working at very high speed, and lower work satisfaction were associated with both types of work–family conflict in all countries.
