Is it normal to feel every bit of emotion from this issue?

Ok, I've had multiple issues with this coworker. He is an employee there which I fill in for on his days off. He's maybe worked there for nearly 7 years. Which this guy is pretty well organized and is a neat freak. We both work the Am cooks position at a nursing home.

I feel ridiculous from what happened today. I wrote him a note a couple days ago from when I last worked saying I need help with a little extra prep being nice. So when I came in today he criticized every little thing I apparently did wrong when its everybody that works there, not just me. Yes, I am no where near perfect but what make him think that lieing makes him better. I had told him while we were talking that I didn't appreciate it when people would talk behind my back rather than in person. He does that to too many people thsre and I can't stand it. There is no point about complaining behind other peoples backs.

This guy is manipulative and not in reality. I have no trust in him because he lied in front of me and has done it many other times.

Of course I was nice during the talks even though I let him know how I felt about not liking people make assumptions and complaining. I thanked him after the converstion because it was an opportunity to let me think further on dealing with people like him. I do need to get use to people like him because there are many like him out there. You just need to be respectful to ever person in existence though but also have respect toward yourself at the same time.

What would you do in this situation?

I've already had to deal with this before, I had to talk to my supervisor to have him actually do his work. I hope to talk to my supervisor tomorrow and see what his perspective is on what this employee had told me, I trust him.
