Is it normal/legal for a lead/trainer to ask everyone that you're working with if they should keep/fire you?

I overheard my coworkers say that my lead ask them if I'm good for the team and they told him no. I guess he didn't ask one of them because he said "if he ask me, I'm going to tell him no too". Quite frankly I don't think it's fair or legal. I kinda feel like I'm being laughed at cause they know something that I dont. Can he do that?

Its unfair to share your opinions of someone behind their back? You are doing that right now.
