Q: We have an employee due to return from maternity leave soon. Her role is full-time and she has asked to return part-time – two days per week. Her current replacement has stated they would be happy to stay on part-time as well, so we would like to approve this request to create a job-share.

We do however have concerns that if the replacement employee were to leave down the track, we may find it difficult to replace them due to the role being on a part-time basis. Is it possible to include something in the contract that this flexible working arrangement is only possible if we are able to recruit someone to fill the full-time requirement of the position?
