a little rant…
I work between two teams at work but work with them on a very regular basis, however I always see each of these two groups going out on social media. For example, one of them in one of the groups had wedding this year and I was the only one not invited.
in one of these groups there is someone that started at the beginning of this year, and has already made it into the clique they do things outside of work and have even been away together.
