Employer about to let me go?

My manager told me this week that he doesn't "have confidence in me." I made two mistakes in work over the past fortnight. I am three months into a six month probationary period of a three year contract.

I've a meeting on Monday, should I expect to be let go? What should I ask them at the meeting? I haven't had my first performance review yet. This is new to me as I thought I was doing okay in work but now I think they want me out.

Wait until Monday, then you will know your fate one way or the other. Sounds to me you are better off out of that company.
