It's nice to have friends. They are there when things go wrong, motivate you to do better, and warn you when you are headed for trouble.

Words can get one black-balled at work, although unfair, it happens. Check local labor laws. Find out what you can about accessing your file to see what others may have said about you. If what has been mentioned, is happening to you, then do what you must. If an apology is necessary, make a verbal and written statement to those you have offended. Find ways to resolve issues. Maybe you might have to take on an additional project, stay later, or do something else to gain your good reputation back with others. Seek employment if it gets too hot to stay in the kitchen!
