I have a coworker who constantly mumbles under his breath impolite things about me or other coworkers. I find it very rude, because others can clearly hear him, although it's possible he is unaware that we do hear him.

His mumbling always consists of complaints about anything we do on the job, to the point that it seems he has an issue with everything we do in our workplace. Yet, he never addresses his complains directly to anyone.

He also rolls his eyes or sighs whenever you assign him something he doesn’t want to do.

I don’t know how to get him to stop this behavior, and it's not just my problem - he disrupts the good feeling of our entire workplace.

I am reluctant to confront him directly because I don't want to cause personal enmity between us. What should I do?

    What does your manager say when you ask about this? And have you looked at answers to other coworker questions?

    What is your business relation to this co-worker? Are you his manager?

    By the way, I'm not the one who downvoted/mumbled about your question, but I assume you're getting downvoted because clearly you know the solution to your problem, you just haven't implemented it yet: "maybe I should say something directly to him because he just really bring the mood down."

When people are rude to you, tell them to stop being rude.

"It's not okay to complain about me just because it's barely audible. I need you to stop. Are your eyes hurting, or are you rolling them to be rude? You know I can see you, right?"

When people are rude to you after you told them to stop, you take it to management.

When management lets people be rude to you, you find a place to work where people aren't jerks.
