By written agreement, an employee may take paid annual leave before it has accrued. The agreement must state how much leave will be taken in advance and when it starts, and be signed by both and by a parent or guardian if the employee is under 18 (Schedule F is an optional form). The employer keeps a copy as an employee record. If employment ends before the leave taken in advance has been accrued, the employer may recover from money owing at termination the pay for the unaccrued part.
