Need help here folks about my 'rights at work'.
Our Christmas overtime sheets were up well in advance so several weeks ago I had agreed to do the shifts on the sheet. I've agreed to stay an extra hour or to or do an extra shift if we're short on numbers and have generally did a lot of favours for Sainsbury's.
However, tonight I went to clarify what shifts I was doing this week and see if there were any more but to my annoyance I found out that they've changed my Thursday 4-10 to 4-8 and Friday (New Year's Eve) 2-6 to 2-7 without telling me. I have not agreed to these hours and they have did this behind my back, what can I do about this?
If they had simply asked me then I would have changed the shifts no problem at all but it's the fact that they have changed them without my consent that has annoyed me and I am not having it
