On the plus side, they can't touch your days off and there is no junior manning.
That said, days off are not necessarily awarded in accordance with seniority. For example; you are number 1 on reserve and you don't get the first weekend of the month off, but the number 2 guy gets it because it would set you up for a sequence of days on that is not useful to the company.
Also be prepared for the 3am wakeup call to put you back on rest for a 2:30pm showtime to have you work well into the night.
Full disclosure, I'm at YX (republic), but it is all the same contract.
