Pregnancy discrimination is any discriminatory practice that is based on a person being pregnant, previous childbirth, and any related medical condition related to the pregnancy.
The employer must treat a pregnant employee exactly the same as employees who have temporary illnesses or conditions. Generally, employers cannot refuse to hire a pregnant woman because of the pregnancy, cannot force a pregnant woman to go on medical leave until delivery of the baby, or in any manner treat a pregnant woman any differently than employees who have a temporary illness or disability.
What this means in the real world is that the employer is only required to hold open a pregnant woman’s job if the employer also holds open jobs for those who are on medical leave. The employer cannot provide extra benefits for the pregnant worker beyond what is provided for all other workers.
