I have an odd situation: I have a coworker who acts like he's my boss. I've already confirmed with higher-ups that it's just not true.
He'll say all kinds of things like:
This is my department.
I run this department.
This is MY analyst. (referring to me)
I need to decide how to manage your schedule.
I'll need to decide if I'm going to let you do xyz.
If you need him (me) to do something, talk to me first, so I can manage his time.
As far as I can tell, he's mainly doing this when other people can hear. He's not even saying anything constructive.
When people walk into the room, a switch goes off, and he'll just start posturing to make himself appear to be my manager.
I told you to do this... I told you to do that.
Finger pointing everywhere... He's just screaming nonsense that has nothing to do with anything just to put on a show. Then, when people leave the room, he flips the switch off and goes back to normal.
I'm pretty sure he's doing it when I'm not around as well.
It's getting very irritating. I pretty much don't even like to talk to him anymore. Every time he comes to talk to me, it's just a useless waste of my time, just so he can posture.
Any suggestions on how to handle this? I've had people come to me because they're confused, and I'm having to correct them. But it would be awkward if I kept going around correcting everyone. Every time he does it, I need to shower off the layer of slime just being near that. I'm not too into screaming matches; they're not my style.
Edit: Someone mentioned that this is the same problem as another post, where someone is just being bossy. This situation is different. Being bossy isn't the same as trying to convince others that you are management. Being bossy is a personality trait. Trying to convince others that you are management is dishonest.
