Manager expecting me to work extra

[user8760098]

I am contracted for 20 hours a week, due to my health I reduced my hours from 37 to 20 just over a year ago.
We are short staffed at work and staff have holidays booked to use before the end of the financial year meaning that we will be even more short.
My manager asked me to work extra hours and I explained I couldn't as I think it will affect my health. She was really shocked that I had told her no and told me that she needed me to work extra.
She is been really awkward now with my rota changing my shifts around and asking me to come in on my days off. She told me today I wasn't a team player for not working extra.
Can anyone give advice on how I should handle the situation?

Your manager isn’t in the wrong to ask you to work more.
You’re not in the wrong to say no. Do you have set days off written in your contract? Or written down somewhere?

It's wrong to say youre not a team player. Shes a crap manager though. I would keep any exchange as factual as possible. I am unable to work those hours. If pushed I am unable due to my health. When you reduced your hours was it done on the basis of your health? Is it a protected charateristic by any chance? If youre not already in a union then I think you should join one to be on the safe side.

No nothing in contract about set hours, when I returned I requested to work mornings as part of my reasonable adjustments as I struggle with fatigue in the afternoon.

I try and keep things as factual as possible with her. Yes i reduced my hours due to my health but I think she thinks that now I have been back a year I'm ok now. Yes I have cancer so a protected characteristic.

Unfortunately then asking and even changing your rota isn’t going against your contract.
Not nice but she’s not doing anything wrong by doing it.
