"Once fully effective, the law will permit all workers who have worked at least 90 days to use accrued leave, allow former temporary workers to claim credit for time worked with their employer on a trial basis, and require employers to reinstate accrued leave banks for individuals who transfer out of the District and return within one year. The law will also dramatically increase the penalties for noncompliance, create a private right of action to enforce the law (in addition to the existing administrative remedy), and create a rebuttable presumption that any employee who experiences an adverse employment action within 90 days of taking leave or protesting an employer's administration of the leave policy has been the victim of retaliation."
