Pregnancy-related discrimination at work is a concern for many employees who navigate the pregnancy and postpartum stages of parenthood while working in the early-to-middle stages of their careers. Although there is legislation prohibiting pregnancy-related discrimination and ensuring accommodations postpartum, empirical evidence indicates many pregnant and postpartum employees still experience such behaviors. In this narrative review, we focus on describing the range of behaviors assessed in studies on pregnancy-related discrimination in several cultures, situating the occurrence of discrimination within theoretical frameworks related to stereotypes and gendered expectations. We also review evidence of employees' postpartum experiences with a focus on the transition back to work, along with breastfeeding challenges related to pumping and storing milk at work. Regarding coping with pregnancy-related workplace discrimination and postpartum challenges during a return to work, we review the importance of social support, including instrumental and emotional support from allies and role models.
