In our coaching practice we meet an increasing number of job-sharers who want to tell their story – and others who would like to explore job-sharing if they knew how to go about it. We are seeing evidence from them and their managers that job-sharing is not just about meeting participants’ personal needs, important though that is. In the right circumstances, there can be significant benefits for 21st century employers. We have talked to those who have had positive experiences, and those for whom job-sharing has not worked so well. In this booklet we highlight what we observe to be the key criteria for success, and the challenges that need to be addressed by all parties.
