In this section I want to talk about work colleagues.
Having mania has resulted in around 90 jobs with 15 professions. I'm now retired. From that 40 years of employment I can tell you that I've now got 2 close friends from those workplaces still in my life. Not many. This to me highlights that seeking compatibility from a work colleague isnt very likely. We meet through working for the same employer not from joining a group sharing the same interests like a hobby or sport. That workplace is the main source of conversation and so when we move on to other jobs we hardly maintain enthusiasm to talk about our old work colleagues and the politics surrounding it.
For this reason to maintain a good level of mental health for your workplace I promote that you keep your distance from other employees. In particular group gatherings like lunch rooms. I've not experienced many lunchrooms where there is lack of toxicity. So what is the alternatives? I'd suggest if you live nearby a good habit is to go home for lunch. I had one colleague that had his favourite spot in a factory corner where he had 2 chairs, one for him and one for his lunch and newspaper. I'd join him at times but he purposely didnt add more chairs as that would defeat the purpose of his preferred isolation.
Another important way to tolerate workmate is not to join them in after hours entertainment. This could be difficult if you are asked as a team to meet for a xmas party for example. My methos (eventually) was to attend for a short time, say 30 minutes and have one drink then slip away. I'd leave many to their choice of buttering up the bosses, getting to know the bosses wife/husband with aspirations that the boss would promote them the next year. It never happened. In fact often the behaviour of some drunken workers at such events or their slip of poor choice of words resulted in them NOT being promoted. The fact is that your private life and the entertainment you like is better served limiting social activities outside working life. Workplace squabbles can be difficult to tolerate.
You want to avoid a workplace that mentally, you end up distressed.
