I work at a massive company, one of the biggest worldwide and I get paid a good salary, enough to meet my needs and to have a little bit to spare, nothing too fancy but a good salary that I'm satisfied with, the company itself is very good and they have a lot of employee benefits.
With that said my department is becoming very toxic ever since a new department head was assigned, and a few managers were swapped around, for example I get called for a meeting with a single email stating “you have a meeting at 3PM to discuss some of your recent work that wasn't up to par to the standards we require”, I try my best for figure out what happened or what are they referring to but I don't get anywhere and the meeting is cancelled, and a lot of incidents meeting that pattern, whenever I bring this up to my friends or family they tell me that I'm lucky I have this job and I shouldn't let that get to me… Etc, I feel like my concerns are not valid and its really putting me in a depressive state, can anyone please help me by either telling me what they think of this or if they were ever in a similar situation?
