Have you discussed with HR? Toxic employees should be their responsibility too.
As others suggested, take note and proof. Start by copying the exact same content you've published here, and complete it with new toxic behaviour.
What will create a body of proofs HR will need and will "expel it" from your head.
I would also meet your manager's manager, this situation has taken too long to resolve and your manager is not doing enough (as far as we know at least). Ask your N+1 whether he has heard of the situation, if he has not your manager is in troubles.
Finally, you have not described how others employees are living through this situation, they may be upset to and be able to help:
- they can report the employee behaviour
- they can react when the employee is not behaving correctly
- they can provide feedbacks, ideas, support?
I wish you all the best, this is a hard situation you're living!
I haven't, because I want the support of my manager, and he's resistant to going to HR because he is afraid of looking bad to our director. Really crappy situation.
Another thing is: it's really difficult to point to specific cases that really are "HR-worthy". That's the nature of passive-aggressive behavior. His treatment of another engineer, who has since been fired for performance, early this year really did qualify for HR based on how distressed the other employee was.
I think I may have to bring this up to my manager's manager, since my manager doesn't want to. It'll hurt my relationship with my manager, but I think this is feedback he really does need to hear and receive, or he'll just keep tolerating competent jerks on his teams.
Several other employees have had issues with him. The sense I get is they're really just seeking peace at this point and it's clear they're avoiding him. Since he's been there since the beginning he knows a lot that no one else does, but they rarely approach him for help -- he's made it clear to me in early 1:1s he isn't interested in investing more time in trying to up-level his peers.
He does have a good relationship with a junior engineer on the team, though, and may be developing a good one with another engineer that he probably has more respect for than me.
Your phrasing makes it totally HR worthy to my mind, especially if the only thing justifying keeping him (experience) is not there.
I was going to give you more advice, but actually here the only one that matters : get counceling/coaching help outside the company, with someone specialised in work related topics. You need someone on your side, to listen, give you fact based advices, discuss strategies, challenge you.
It's a very stressful situation, get all the help you can!
