Before the late 1970s, many workers lost their jobs for becoming pregnant. Employers saw pregnancy as a sign of being “unreliable” or “not committed,” leaving workers with few legal options. Some were forced into unpaid leave, while others lost promotions, were removed from schedules, or were fired under the guise of “company policy.”
The Pregnancy Discrimination Act changed this by defining pregnancy discrimination as sex discrimination. It requires employers to treat pregnancy and related medical conditions like other temporary health issues. While discrimination still exists, this law strengthens workers’ rights to contest unfair treatment. If you’re facing pregnancy-related workplace issues, a proven pregnancy discrimination attorney in Los Angeles can help you understand your rights and the next steps to take.
What the Pregnancy Discrimination Act Is and Why It Was Needed
The Pregnancy Discrimination Act (PDA) was passed in 1978 as an amendment to Title VII of the Civil Rights Act. The law was created because pregnancy discrimination was widespread, and courts had previously allowed employers to exclude pregnancy from disability and benefit policies.
The PDA clarified that discrimination “because of sex” includes discrimination based on pregnancy, childbirth, or related medical conditions. That means employers generally cannot make negative employment decisions—like firing, demoting, refusing to hire, or cutting opportunities—because someone is pregnant or might become pregnant.
The Biggest Shift: Pregnancy Must Be Treated Like Other Medical Conditions
One of the most important changes was the requirement that pregnant employees be treated the same as other employees with similar ability or inability to work. Employers can’t create special “pregnancy rules” that treat pregnant workers worse than workers with other temporary conditions.
This principle affects many decisions: job assignments, leave policies, time off for medical appointments, and benefit access. If an employer makes exceptions for other conditions but refuses similar flexibility for pregnancy, that can raise serious legal concerns.
Hiring and Promotions: Closing the “We’re Worried About You” Loophole
Before stronger legal protections, employers often refused to hire or promote pregnant workers under the guise of concern, claiming the role was too physical or that pregnancy would create scheduling issues. The PDA made it harder to hide discrimination behind “protective” explanations.
Employers generally cannot refuse to hire or promote someone because they are pregnant, might become pregnant, or have pregnancy-related medical needs. The decision must be based on legitimate job factors, not assumptions about pregnancy.
Pay, Scheduling, and Job Assignments: Where Discrimination Often Shows Up
Pregnancy discrimination isn’t always a dramatic firing. Often, it appears as subtle changes: fewer shifts, less favorable schedules, removed responsibilities, or being pushed into lower-paying tasks. Some workers are isolated or treated as a burden.
The PDA helps address these quieter forms of discrimination. If a worker’s job conditions change soon after announcing pregnancy—and those changes don’t match business reality—that timing can become important evidence of discriminatory motive.
Leave and Benefits: Ending Pregnancy Exclusions
The PDA also impacted benefit plans. Employers can’t single out pregnancy for worse treatment in health coverage or leave benefits compared to other medical conditions. If an employer offers disability leave or medical leave for other conditions, it generally cannot exclude pregnancy-related leave.
This doesn’t mean every employer must offer paid leave. But it does mean pregnancy can’t be carved out as an exception that gets less support than comparable medical needs.
Harassment and Hostile Work Environment

Another major impact of pregnancy discrimination law is recognizing that discrimination isn’t only about decisions—it can be about treatment. Offensive comments, pressure to resign, jokes about pregnancy, criticism for doctor appointments, or hostility about pregnancy-related limitations can create a hostile environment.
The PDA’s framework supports claims where pregnancy becomes a reason for workplace mistreatment, not just a reason for employment actions. Documentation of repeated comments and patterns of hostility can become key in these cases.
Medical Restrictions and Accommodation: How the PDA Shaped the Conversation
The PDA pushed employers to take pregnancy-related medical restrictions seriously. Many pregnant workers have temporary limitations: lifting restrictions, the need for more breaks, limitations on standing, or schedule changes for prenatal care.
While the PDA itself focuses on equal treatment, it helped shape how courts and employers evaluate accommodations. If an employer provides modified duty or accommodations for other employees with temporary restrictions, refusing similar support for pregnancy can be discriminatory.
How the PDA Works Alongside Other Modern Protections
Today, pregnancy rights often involve multiple overlapping protections. Depending on the situation, workers may have rights under laws related to disability accommodations, family and medical leave, and newer federal and state laws addressing pregnancy accommodations.
That overlap matters because employers sometimes claim the PDA is the only rule, when additional laws may also apply. Understanding which protections fit your circumstances can make the difference between a narrow complaint and a stronger claim supported on multiple legal grounds.
Retaliation: A Major Part of Modern Pregnancy Cases
The PDA’s impact isn’t limited to discrimination itself—retaliation is a major issue. Workers who report pregnancy discrimination or request fair treatment may face retaliation through discipline, termination, poor performance reviews, schedule cuts, or isolation.
Retaliation claims often rely on timing and documentation. If negative job changes happen soon after a worker discloses pregnancy, requests changes, or reports discrimination, that sequence can support an argument that the employer acted improperly.
What Evidence Often Matters Most
Pregnancy discrimination cases are often proven through patterns rather than one “smoking gun.” Useful evidence can include:
- Emails or messages about pregnancy, scheduling, or performance
- Sudden changes in assignments, pay, or hours after disclosure
- Performance reviews before and after pregnancy announcement
- HR complaints and written reports
- Notes from doctors about restrictions (when relevant)
- Comparisons showing how other employees were treated for similar limitations
The PDA Changed the Rules—and Gave Workers a Stronger Voice
The Pregnancy Discrimination Act (PDA) improved workers’ rights by treating pregnancy discrimination as a type of sex discrimination. It requires that pregnancy be handled like other temporary medical conditions in employment decisions. While it didn’t immediately stop unfair treatment, it set clearer rules that employers can’t ignore with outdated beliefs or excuses.
If your workplace views pregnancy as a problem instead of a normal part of life, the PDA and related protections can help you. By keeping careful records and taking smart actions, you can use these rights to protect your job and challenge discrimination that should never occur.
