ASA member Kristen S. Harknett (University of California-Berkeley) talks to PsyPost about her recent research with Kevin Bruey (Harvard University) and Elizabeth Kuhlman (Stanford University) in the Journal of Marriage and Family, "Predictably Unstable?: Precarious Work and Precarious Relationships in the U.S."
To explore whether routine instability in work schedules disrupts marital and cohabiting relationships, the researchers analyzed longitudinal survey data from 6,918 hourly service-sector workers at large retail and food service companies who were either married or living with a romantic partner. Their findings indicate a consistent link between erratic schedules and relationship breakdowns for both married and cohabiting couples, with men’s schedule instability tied to a higher risk of divorce than women’s schedule instability.
While money problems are a known relationship killer, a new study uncovers another threat: unpredictable work schedules. Researchers found that erratic shifts and last-minute changes increase the risk of breakups for hourly service workers.
