Scheduling hasn't "required" a single pilot to fly in violation of the contract. It is up to each and every single pilot to know their contract and to learn to say, "no" when asked or told to do something. Honestly, half of the schedulers don't know or understand our contract either so I'm not surprised. But it's still the responsibility of the pilot. Have an issue with something? Use the buddy system and ask a friend and if that fails phone your rep. That's what they are there for.
