I'm currently on maternity leave and applied 2 weeks ago to go back 2 days a week (I was doing 4 days before). They have got someone covering my maternity leave doing 2 days at the moment on a temporary contract, so I said I could either replace her or we could work together doing 2 days each.
My boss came back after a week and said no. His reasons? "One person cannot get the job done in 2 days" (even though that's what's happening at the moment - quite successfully apparently as the requirements of the job have shrunk) and "A job share would be too expensive for us, not in terms of salary but benefits." But I don't really get any benefits, and what I do get (pension) could be just reduced pro rata.
What can I do? Can I claim constructive dismissal? Is this really a redundancy? They clearly want me gone and are using this as an excuse.
