I take it by your name Embraerflyer that you're at a regional where I know CPs can really suck sometimes and there are no options around them. I had my own problems with an assistant in EWR at Coex and I remember horror stories from Chautauqua friends who had a lot of problems with theirs. Just protect yourself, be wise and get your money's worth out of the union. If they suck, then protect yourself by whatever means you need too.

Also, keep in mind that CPs have a lot of pilots out there causing problems, idiots trying to run an airline from their cockpit and so on. Think through anything you do before you do it.
