I'm the youngest amongst my colleagues by about twenty years. One colleague, Mary, is extremely difficult but I am polite and act as if her muttered remarks aren't heard.
I'm also more senior than this colleague, same small workplace but different roles. I job share.
I spoke to my job share colleague about getting gifts for the whole team this Christmas. She replied "We're all going across the street to Mary's cottage for an afternoon tea". I was a bit gutted to not have even been consulted about this (given that me and my job share are the managers) particularly when the whole team know that I am shielding and they know I don't socialise indoors particularly in a teeny tiny cottage with having to sit three on a two seater sofa. They are all 100% aware of this. I feel like I'm a vegetarian and they booked a Christmas lunch at a steakhouse. To top it off I heard today that Mary has organised gifts for people (very nice but not really her job, that's my job!) which are bottles of prosecco. Again they all know I can't drink because of my medical condition and its a standing joke that I don't know a thing about alcohol.
I feel gutted to be honest, Mary intentionally undermines me in small but significant ways whenever we work together. Now she is hosting the staff Christmas party and I can't go. Help!
