I've been doing this for nearly 8 years (at least to some degree). While it is not guaranteed I work Saturday / Sunday, I'd say 90% + of my work schedule is friday / saturday.
Next month I do get friday / saturdays off (work sunady) but this is rare.
Quite frankly I don't care that much as long as I'm working 40 hrs and getting paid good money. However, I think if I could take a 5k paycut to finally have a normal schedule, I might TRY it, but most likely would eventually take the 5k back because you get used to either way I assume.
I should mention I had about 5 months where i worked mon-fri and rotated saturday shifts about once a month. I got used to both. Time off is time off.
