Hey guys, I picked up a WS showed up and they keep slipping the departure time. It was a one leg out and next day back worth 10.5. what is my obligation to sit here in the crew room? Also when they can't get me back the next day within 4 hours of scheduled arrival what are my options?

If they cancel the trip what do I get paid? I've been here 5 hours now... hopefully it's not just assignment pay.
