Without going into specifics my line manager and I have had a disagreement about something they did - basically they excluded me and did not send me key information. That's an aside. I am on leave for the next 2 and a half weeks - today was my first day on leave. My line manager knows I am on leave, she authorised it.
I received an email today in which she has asked me to reflect on the issue whilst I am on leave. It was a shitty email with inaccuracies, basically asking me whether I should continue on a project. So, she knows I am on leave. There is every chance I would not have seen the email because why would I be checking emails. But clearly she has sent the email knowing that I would check - and the email can do nothing but spoil my holiday. It won't because I am now at peak anger, which is when I go cold and ruthless. But is there some rule etc that can stop employers doing that? Sending shitty emails when on leave?
