I was told by many not to sign it because if they use me to drive and I don't sign it they have to pay me full pay rate instead of seasonal pay rate.
Ok, quick question here. Do you have any cognition or recollection handicaps?
I ask this because the very second sentence of your post states that you asked many and they ALL told you NOT to sign. And here you are...
Do you expect an internet chat room filled with knuckle dragging mongoloids to assuage your leeriness about not signing the list? Maybe I'm guessing here but the people's opinion who actually work in your building, and who are in the know about things that happen there, are of less importance than your new frens on the internet. OK, well good luck.
By the way, sign the bid. If you don't, you won't work.
