The Pregnancy Discrimination Act of 1978 prohibits discrimination based on which conditions?

The Pregnancy Discrimination Act of 1978 extends legal protections against discrimination for individuals who are experiencing pregnancy and any related medical conditions. This means that employers cannot treat women unfavorably due to pregnancy, childbirth, or any other related medical issues. This encompasses a broader spectrum than just the state of being pregnant or having given birth; for instance, it includes conditions such as gestational diabetes or severe morning sickness.

This comprehensive approach ensures that women are not only protected during the time of pregnancy but also during any medical situations that could arise as a result of their pregnancy. The law aims to provide equal job opportunities and safeguard the rights of women in the workplace, fostering a more inclusive environment. Thus, the correct choice reflects the law's intent to cover both pregnancy and its related medical conditions, promoting fairness in employment practices.
