If you are disabled and work for an employer with 5 or more employees, you have the right to take unpaid pregnancy disability leave for up to 4 months.
Family Medical Leave Act (workplace more than 50 employees)
Under the Federal Family and Medical Leave Act and the California Family Rights Act, female employees are entitled to up to 12 weeks of unpaid leave for the birth of a child (and for other reasons not mentioned here). This leave is unrelated to pregnancy disability leave and may be taken in addition to any disability leave the pregnant employee is entitled to under the Fair Employment and Housing Act. Healthcare insurance coverage must be maintained during this leave.
