Tell him that behaviour is unacceptable. Don’t mince your words, be explicit and direct. Loop in HR/advisor/whichever higher ups and let them know if the behaviour continues. You don’t have to tolerate yelling, berating, mid-meeting video watching from anyone.

If he’s unwilling to stop that behaviour or unwilling to try cooperate, make sure higher ups know. There’s not much you can do if he just refuses to cooperate (just like anyone else).

If he IS willing to try cooperate, asking him directly (or asking HR/advisors/etc to mediate a discussion) about what he needs to effectively cooperate/what isn’t working could help you find ways of working together. For example, if he’s feeling that his ideas aren’t being heard/discussed because he doesn’t quite know how to interject/take part in a group discussion could be alleviated by making sure to ask him for input explicitly during group discussions. Not saying that’s the case or a perfect solution, and that frustration certainly doesn’t justify unacceptable behaviour, but yeah that kind of thing might help?

Hope that gives you some ideas. Shitty group members of all stripes are a frustrating experience. Good luck!

Thank you for your advice. I agree that group dynamics are most likely very hard and can be super frustrating for him, and maybe that causes his disruptive behaviour.

As an Autistic person, thanks for going to the effort of trying to understand this dude and find a solution. It mostly sounds like he’s just an arsehole, and it shouldn’t be your responsibility to teach him how to work in a group or communicate needs he might have, so yeah, thanks for making the effort.
