I feel the same way. I have that WOWOWOOOO schedule, and it's not bad.
At my last employer, we had a 24/48 w/o Kellys. Understand that if you too little sleep on shift, your next day is ruined or at least half ruined. And yes, you're always going back to work.
Understand that if you work for a department that forces OT on you, holds you over or recalls you due to staffing vacancies/sick leave, you could effectively be doing a 36/36 or 48/24. Been there, done that, never again.
With my schedule, they can't hold you past 12 hours, so no 48 hour shifts. Also, if I take a day off, one of my thrice monthly four day breaks becomes a six day break.
Also, due to FLSA law, after 212 hours, all work hours are time and a half. If you're going to do OT, make sure that you do it early in the 28 day FLSA cycle, so you can double dip. What that means is, you do OT, and it counts as time and a half. It also counts towards the 212 hour threshold, so every hour you do, if you do it in the first week or two, will get you an extra half hour's pay in the back end, the second check of the cycle. It's basically free money. So, for every 12 hours you work, you're getting an extra half hour pay x twelve hours, so it's a free six hours of straight pay. On my check, it shows up as "REG>FLSA Threshold," and it was an extra $1,270 gross on my check. If you do OT, just time it right. Some pay periods have more hours than others, so get it all on paper, then figure out when you want to do some extra hours.
