I currently work full time and have asked have applied via flexible working to reduce my hours to 90% FTE.
Lots of people have flexible arrangements in my office, so it's certainly not unheard of.
My boss has said I can do it for a six month trial period using my annual leave (so not reducing my hours contractually). I do not want to do this because I will have no leave left, especially if they then say the trial hasn't worked and I am not allowed to continue.
What can I do? I am not averse to it being a trial period, but would rather that I genuinely cut my hours in that time and not have to use leave.
