It may be culture to the workplace. At a prior job one of my co workers acted like our mother. She gently insisted we would do things together. She made it clear there would be no back biting and we were a team. Every Friday we walked over to the north end for Pizza and about every 3 months we all went with our significant others out for dinner. She was a leader. We were a team.

However, when I came to the job I work at now, I tired that.. Unfortunately the culture of this place was back biting and game of thrones type sneaking around. Not only did I get resistance on even having a monthly lunch, they actually told their bosses I was trying to organize these things as if I was trying to form a union or something. I realized that was a mistake. The culture of the place is cliques and mean girl behavior and now, I do nothing outside of work with anyone. I feel for some of my co workers who are like 1 year temporary workers who think it is strange or mean of me to refuse to do anything with them outside work. But once you learn to play the game you need to play it. I don't want it to be this way but, it is and you just have to be that way. It isn't personal.
