An employee who is sick may request in writing to terminate additional maternity leave if the sickness occurs during the last 4 weeks of maternity leave (whether or not part of such leave is postponed under sections 14B or 14C) or during the additional maternity leave; the request may be submitted on her behalf. An employer who agrees to terminate must set an agreed termination date that is not earlier than the commencement of the employee's sickness and not later than the date the additional maternity leave would have ended under the employee's notification given pursuant to section 14(4) or 14B(8). The reference to the last 4 weeks is to be read as the last 2 weeks where transferred paternity leave is taken, together with that transferred period.

An employer who receives a request must notify the employee in writing of the decision as soon as reasonably practicable. Where additional maternity leave is terminated under this provision, any subsequent absence from work due to sickness is to be treated in the same manner as any other sickness absence and the employee forfeits entitlement to the additional maternity leave, or the part of it, not taken on the date of termination.
