“Schedulers attempted to make him DH after we finished our trip in Seattle to be in position for reserve in another city. The contract did not clearly show who was correct.”
You cannot be made to DH to another city and then sit reserve in a hotel, unless you have a flight assignment out of that city that follows that day or after a layover. This was addressed a couple years ago by the union.
You are also entitled to your full 2 hrs from the first phone call/contact.
