Answer: 12 weeks
Explanation:
If an employee's family member is seriously ill, the employers are required to allow the employee up to 12 weeks off.
According to the Family Medical Leave Act, it should be noted that the individuals who work for the employers who have 50 or more employees can be given about 12 weeks of unpaid leave in a year which they can use to take care of family members that are seriously sick or care for new children or seriously ill family members, or for themselves if they're seriously sick.
