You're going to be on reserve, which is 10 days off (and they can juniorman you below the 10 days, but I'm not sure how frequently that happens). Then they're probably going to use you a lot, so they might activate you for any mix of day trips to working 6 days straight. No one can predict how many days you might get back to back. It might only be 2 in a row, or you might get lucky once in a while and get 4. Within the past few months I've seen some new FOs get sweeter schedules (more credit AND many more days off) than the "senior" lines, by bidding build-up lines... but that of course is luck of the draw. Mostly I hear the reserve is terrible.
