The Family and Medical Leave Act states that employees are allowed to take up to 12 weeks of unpaid leave for the adoption of a child. The Option B is correct.
This federal law was enacted to provide job-protected leave for eligible employees to balance the demands of the workplace with their family needs.
Under the Act, employees who have worked for a covered employer for at least 12 months and have completed 1,250 hours of service during the previous 12 months are entitled to take up to 12 weeks of unpaid leave for reasons such as birth or adoption of a child.
During this leave, the employer is generally required to maintain the employee's health benefits, and upon return, the employee is entitled to be restored to their previous position or an equivalent one with the same pay, benefits and terms of employment.
