I was diagnosed with cancer Jan 2020 and returned to work Jan 2021, as part of my reasonable adjustments I reduced my contracted hours down and requested to work mornings as I suffer with fatigue in the afternoon. This was agreed with my manager.
A new manager has now started and she has changed my shifts to afternoons due to another member having childcare issues. I explained that I still need the adjustments as I still suffer from fatigue but she told me she needs me to work afternoon shifts now.
Can anyone offer any advice on how to deal with this situation?
