The Society for Human Resource Management (SHRM) said employers’ leave policies are often reinforcing gender role stereotypes by providing more leave for mothers.

According to the Paid Leave in the Workplace Survey, women on average receive 41 days of paid maternity leave, while men receive 22 days. This particular imbalance, according to SHRM’s director of workforce analytics, proves that employers still expect women to take on a majority of the care for a new child. This type of gender inequality could discourage fathers from taking a similar amount of days off to help with a new baby.

The United States Equal Employment Opportunity Commission chimed in with the fact that these type of policies are not discriminatory, but implementation is key. Employers should really distinguish between types of leave. “Leave related to pregnancy, childbirth, or related medical conditions can be limited to women affected by those conditions,” the commission says in its Enforcement Guidance on Pregnancy Discrimination and Related Issues.

SHRM found through its survey that these kind of differences in paid paternal leave benefits could easily be questioned by employees of both sexes on the grounds of gender equality and equality between same-sex couples. SHRM is warning workers to expect their employers to start pushing back on these policies.
