Well, I've always wondered if someone, somewhere has similar experiences to mine at work. Because I already call it karma. Or maybe all people feel the same to some degree, but don't admit it, or deal with it better than me, are stronger, or have accepted that this is life.
From my recent experiences at work, I understand that people go into survival mode - staff behave hypocritically with their colleagues and badly with new hires in order to protect themselves from losing their jobs. They are constantly in a defensive-attacking position. Bosses also behave in an aggressive manner, mostly out of fear for their position. I never realized until now that this behavior (hostile and aggressive) could be caused by such reasons. But I think things are even getting deeper and worse in recent years, because humanity is headed in some unknown but rather scary direction.
Well, I hope all this is not relevant to you, and indeed your fears are unfounded!
So, good luck in your new job! 😊
