Family-Work Conflict

The goal of this clinical trial is to learn if an online program treats stress in working couples. The main questions it aims to answer are: * Does the 3-week online program lower stress for participants? * Does doing the program together work better than doing it alone? * Does the program lower conflict between work and home life? * Does the program improve job and family satisfaction? Researchers will compare four groups (both partners, only women, only men, and a waitlist) to see if doing the program together works best to lower stress. Participants will: * Fill out online surveys at the start, after 3 weeks, and 6 months later. * Use a 3-week online program to manage time and lower stress. * Read short texts and track their daily habits. * Talk and plan with their partner if placed in the joint group.
