How can you tell if you are about to get fired from your job?

My boss has been acting kind of weird towards me for the past few weeks. Usually she is very friendly and talkative, but lately she has been very standoff-ish. My coworkers really don't talk to me. I have been working here for about 8 months. I haven't done anything to get fired, but my job performance is rated by our customer service surveys. I have maintained high customer service scores since I have been here.I am in a union, and my department is supposed to get a raise every year, and everyone in my department got a raise except for me. Should I be worried? Is this something I should talk to my boss about?

Just come right out and ask your boss if there is a problem and tell her exactly what you've told us. It is only fair that you should know what is going on at work. This way you won't have to sit and wonder and make yourself crazy and it's not fair to be treated that way at work.
Reply:Usually, if you're about to get fired from a job, they cut your hours back to nothing (if you're working part-time). Why not ask your boss why you didn't get a raise? Ask her what she thinks you should be doing better, and then do it.
Reply:Request a meeting with your boss to find out what's going on. Have your union representative there.
