So anyways, this morning I had to tell my boss that another member of our team who is a peer is not cleaning something as it's supposed to be cleaned.
I tried using the peer feedback model (he's not my boss, he's a peer) and I basically said, with asking if I could give him some feedback.
"When you do not shut down the grill from 4 AM to 5 AM to clean it properly, it puts our customers at risk of getting ill from the chemicals we use, customers make me out to be the bad guy because I am doing it and you are not and the grill does not come nearly as clean, how do you think we can fix this?".
Now, obviously he was very unreceptive of this feedback, accused me of brown nosing our boss, etc, etc.
Now, as I said, this morning I confronted my general manager with this situation, and explained that it was causing a great deal of problems for me and his crew. He said he would talk to him about it. Now, my boss, is not the most discrete guy so I know this conversation started off with "Zack said".
Now, this peer helped me get where I am today, but he's very abrasive, not someone that I relate to in the task of management. He's a little rude, and the conversation is likely to involve profanities and such. Now, obviously, I can use the feedback model, but it's not going to do much good, because he believes that his attitude is acceptable in the course of communication.
Now, I am a person where, when someone else gets confrontational or angry with me, I go back in to my shell, and sorta hide. I back down and honestly, this is a topic that due to my belief in food safety and the fact that profitability is at risk here, I cannot back down on.
So... keeping in mind that I'm bad at confrontational events, how should I handle it?
