Sometimes we must choose between what is right and what is easy.

And that is where I find myself.

Relevant background I am employed by a parent company but work in the subsidiaries. I can choose where I work and which smaller companies I deal with, parent company support me and renumeration is excellent, they would not question why I no longer wished to work for a smaller company.

Problem. I have recently started working at a company that the parent company has recently acquired. It is clear that the manager is a bully, a particularly horrible one. If you do not fit in with his ideals he doesn't just force his staff leave he makes it incredibly difficult for them to be employed by any local company by badmouthing them. I have proof of this.

I can walk away or I can bring this to the attention of the parent company. This will mean he knows that I have raised the issue and I have no doubt that he will try to jeopardise my working life and possibly my social life.

I feel I should do what is right, but the repercussions personally could be huge. Wwyd?

Yabu - look after yourself
Yanbu- someone needs to make a stand no matter what it costs you.

The thing is it’s not just one dysfunctional person but a whole system that he’s manipulated into being powerless to do anything about him. Psycho /sociopathic boss territory by sounds of it.

So while you want to stand up & champion his victims, you”ll have to take on not just an individual but a whole system & be able to rely on individuals’ word to back you up or come forward & testify. How do you know he won’t turn anyone against you, intimidate others etc to undermine your claims etc.
And if you’re so sure of how retaliatory he could get & the lengths he’s prepared to go to get revenge, I would keep well out of it, despite how ethically this goes against your (noble) principles. I would feel the same - knowingly not supporting others from being equally mistreated is incredibly hard. But you have the luxury of choosing to not work in that subsidiary & so I would make the most of that & get out.
Whilst the ones you will be leaving behind don’t have the luxury of this choice, they can & should seek other employment themselves elsewhere. As the only thing that will get this person brought to the parent company’s attention is a mass exodus of staff. Then they have to question why. But even then, if he remains & his management continues to yield results, they still may not do anything about his behaviour if he continues to generate profits get result. Brutal but sadly only too common IME.
