I didn't realize that WSC was a legally binding document - I thought that it just served to help explain the scheduling provisions of our contract. From what I can find, the 9 hour leash is NOT codified in the PWA, it's IMPLIED as a MINIMUM leash thanks to the 3 hour prior acknowledgment requirement. As an example - let's say I'm on long call, and I noticed that I missed a call from scheduling so I use my iCrewMax app to unofficially check my schedule. And let's say that I notice, unofficially, that they have assigned a trip that reports 24 hours from now. I now have 21 hours before I have to officially acknowledge the assignment, not 9. Correct?
