At work we have been really busy. As a result, I've struggled taking my lunch hour until late afternoon. I have not mentioned this to my manager, however as her office is right near me she notices I'm at my desk and haven't left for lunch yet. She brought it up in a conversation with me and seemed to be implying that it's my fault and I'm refusing to go for lunch.
The way I see it is I prefer to take my lunch in the afternoon as the workload slows down a bit, I also prefer eating lunch later on in the day. My colleagues are the same but as my manager's office is right near me so she seems to have focussed in on me. I do take my lunch break every single day and I wait until there's a good time to go, sometimes that's 1pm but more often it's around 4pm.
As a result, my manager is now using my late lunches as evidence of how understaffed we are. She is also putting forward that we have defined lunch times rather than the flexible approach we currently have.
I feel like I'm in the wrong but didn't realise. I prefer a late lunch anyway as I have a 2 hour commute at the end of the day so often don't have dinner until 8-9pm.
