My coworker is acting like he is my boss
So i am working as a junior quality engineer, and my quality manager quit a week guy, really great, taught me a lot of things, great boss, strict but fair.
So its a contruction project and now our team is 2 senior engineers and me ,
This one dude doesnt really work a lot, just warms his seat up, never goes to site, doesnt do any work, The project manager told him to take more responsibiltity until the new manager joins in 2 weeks basically take over some of the managers work load, but it just me and the other engineer who split it and this dude decides to start micro managing me asking for logs of every work i do every 20 mins to show it to the PM and he doesnt understand the logs and me explaining it to him is like talking to a rock.
He doesnt know shit nor does he do anything.
I tried talking to the PM about this, but he shook me off saying learn to work in a team.
I could barely do my own tasks and i guess i didnt do anything today coz he kept disturbing me and not letting me work. He has taken over the managers office and has started to introduce himself as a manager to subcontracters, even though he isnt.
This has been happening for 2 days and i already want to beat his ass.
What can i do? Do i just file a complaint? Or just scold him? I dont want to lose my job coz i am a fresher, its my first job its been 6 months and office politics is too much for me and it is a really good firm.
