For example, it would be illegal for an employer to engage in pregnancy hiring discrimination—to refusing to hire someone because she is pregnant. If a supervisor believes your pregnancy or maternity leave will negatively impact their business and fires you, you've experienced pregnancy discrimination.Pregnancy discrimination is against the law. The EEOC enforces three federal laws that protect job applicants and employees who are pregnant. Firing an employee or cutting hours due to pregnancy or expectations about pregnancy are also examples that are far too common. Many get "iced out" instead. For example, coworkers may stop sending you invitations to gatherings outside of work. Shockingly, pregnant women and mothers report more discrimination and poor treatment at work now than they did a decade ago. Expecting mothers in Pennsylvania often choose to continue working throughout their pregnancy. The Pregnancy Discrimination Act applies only to employers with 15 or more employees, but many states have similar laws that cover smaller employers.
