I'm doing that and getting the shirt. This is my first contract so I won't preach. I'm on contract with a bunch of very nice captains and what they've taught come's down to to things, don't exceed the aircraft limits and don't exceed your own. I know it's already been said, but it should be emphasised. If the captain wants you to do something you're not comfortable with, just tell him you're not happy to do that. If you end up with a company putting you in bad situations leave now, before you become a smidge on a mountain.
That's my opinion
