OK contract gurus...

if I think I'm bought off my next trip due to another guy getting OE...

-what is my recovery obligation?
-when is the moment of truth?
-whats the best case/worst case scenario?

I've read the contract as best I can and as near as I can tell it is:

-can fly me on my original footprint..more or less
-12 hours before they have to tell me or I'm off the hook
-best case..I'm done and being paid/worst case..crappier trip given to me 12:01 before the original sign in

any/all right? if I'm not assigned by 12 hrs prior, but told I'm removed, am I on reserve? (SC?)

??
