Before I went on maternity leave I worked three set days and a flexible fourth day which could be in the evenings or weekends. I applied for this through flexible working but it appears my former manager agreed to it without sending off any of the paperwork.
I am now returning to work following a years maternity leave and my new manager has said she does not agree to this flexible working and that I need to come into work on four set days. This is not something I want to do as I want to be home in the day for my children. They won’t agree for me to go down to three days employment (financially this might not be manageable for us anyway).
I realise I was lucky to get his agreed in the first place but is there anything I can do? As they allowed me to work in this pattern for over a year does that constitute an agreement?
Any help would be really really appreciated
