I work in an office of women, and over the last few months a few cliques have formed. I left school a long time ago, but every day I feel I'm right back there.
These separate groups go to lunch in their packs every day, and behave awkwardly if someone else sits on their table. They have in jokes, and I've seen they constantly message each other in 'group chats' during the work day. After work they go out for drinks without including others.
Even at the staff party, they stayed in their groups. I spent the whole night talking to the receptionist.
I am friendly and try and start conversations with them, but I always get short and awkward responses. It really is like being at high school and it's making me want to leave.
