Let's assume you could "front load"
You will get 10-12 days off per month to start, or 18-20 days on duty. You can only work 6 days in a row before having a 24 break. So to get 18 days packed together, you would need a minimum of 20 days. Figure a day before and a day after for commute nets you 8 days at home. If you only had 10 off duty days, you might get 6 days at home. Either way, that would be a grueling schedule (I would slit my wrists before the end of the month).
Dont forget 30 in 7.
So how likely is it to front load like you want as a new guy? About the same as hitting the powerball.
