About 4 months into my leave, my Maternity Cover asked to go part-time and work agreed, and hired a fixed-contract part-time assistant to help cover the work load. I applied for flex working (to start in 2010), for a 3 day work week and in my application pointed out that an assistant would help bridge the gap between what had been my full time role and my newly requested part-time hours. (This seemed reasonable as they had already put it into practice with MC.
My work agreed to my reduced hours and said that it was possible as a few of my responsibilities would be moved to a newly created position and because, as I had more experience than my MC and the new assistant, I would be able to get more work done in less amount of time. They said though that because of budget constraints, we would have to look at the possibility of an assistant next year. (This didn't really make sense to me as the assistant would be paid out of the money they save from not paying me full time, but I didn't press the issue.)
However, when I went in to talk to HR about my return to work, they started talking about keeping my Maternity Cover on a contract basis for two days a week as a job share. I am gutted. I told them that I wasn't pleased with the quality of his work and thus would have a trouble sharing my job with him but HR just didn't get it.
So, I now feel really tricked and resentful as I asked for and agreed to part-time work, not a job share. I would really rather go back to work full time (or 4 days/week) than share with him.
Question 1: Are they allowed to switch it like that without my agreement?
Question 2: The request for flex working was made to start in January, but there was talk that we would draw up a new contract after I returned to work (full time) in October. Does that mean that until the new contract is signed, there is no obligation to follow through on the agreement made during flex working discussions? So could I pull out or request a different arrangement?
