I'm assuming this is non-unionized workplace ? 🙁

This is what Carlos Castaneda calls the "Petty tyrant" Petty tyrants are the button-pushers, the individuals that have the ability to throw things off-balance for you if you let them. Many petty tyrants are unaware that they are the cause of so much frustration. They are effective teachers because they force the warrior to closely monitor their own reactions and habitual behaviors. The result is mindfulness and the ability to shift the assemblage point, even if ever so slightly, in order to loosen the fixation to the conditioned response that causes the reaction in the first place.

If your bosses behaviour is unacceptable. [b]LET THEM KNOW ![/b]

You don't have to have a stand up row about it just let them know quietly that it's unacceptable and you won't tolerate it.

Capitalism? 🤷‍♀️
Get another job or endure until retirement? I'd suggest HR but if you're really powerless as you say, that probably won't be helpful

I recommend this book:

Take the Bully by the Horns
by Samantha Horn

I had a bully boss and this book helped me.

Get someone to drop a bag of weed onto his passenger-side seat in his car and then call the cops anonymously. HR will not even be able to help him as the cops will take him directly to the squad car. I hear this really works.

I've lost many a job over bully boses.
Try to bully me laigh in their faces and look for another job

Many phones can record now. Video and audio. I suggest using them and THEN go to HR

I would go to the Corporate head and file a complaint

Fite him
