Maternity leave is not federally guaranteed or paid in the United States. Although there has been an increase of women in the workforce, federal maternity leave policy has not changed since the adoption of the Family and Medical Leave Act in 1993. The subjective quality of this maternity leave is likely an important component of what mothers perceive to be decent work. However, no scholars have developed measurements examining mothers’ subjective experiences of the quality of their maternity leave. Therefore, the goal of the current research was to develop scales measuring six domains of quality of maternity leave: time off, flexibility, coworker support, discrimination, microaggressions, and benefits (e.g., pay, health care, disability insurance). In two studies with diverse samples of working, adult mothers, we provide evidence for the factor structure, validity, and internal consistency of the Quality of Maternity Leave Scales.
