PDLL provides for leave for a period of four months. If an employee takes that leave for more than four months, the reinstatement right to the same or a comparable job does not apply unless the employer has a policy of allowing its employee to return to work after taking disability leave for longer than 4 months.
An employer may require that an employee requesting a pregnancy disability leave or transfer provide certification of the pregnancy-related disabliity from the employee's doctor. That certification generally should include the date that the empoyee became disabled, probable duration of the disability, a statement that, because of the disability, the empoyee is unable to work or to perform one or more of the essential job duties of that specific position witout undue risk, until she successfully completes her disability.
The employer may also require a medical return to work release before allowing the employee to return to work, if that kind of policy is applied to other disabilities at the company, which are not related to pregnancy.
