Not sure if I'm being unreasonable or not.
Jacob's join is a frequent event at my place of work and I always cook and contribute. Normally a list is put up on the staff room door. This time there wasn't.
Overheard a conversation today about it, a colleague asked me what I was bringing. Explained I hadn't been told about it and know nothing about it. She said doesn't matter you can still eat something.
Colleague who has organised it is bringing her halogen oven so everyone can warm up food.
Just so happens, I stuck up for another colleague to the person who has organised the jacons join as she is almost impossible to work with. Think bossy, micromanaging, reading your emails etc.
I've got a lot of stress at home atm but to be deliberately left out, is not something I would personally do.
