I do 2 days, 2 nights 4 off, with 18 days off 5 times a year and I f*****g love it, loads of time off to do whatever I please, jobs crap mind, but the time off is excellent.
But if you want an example of long hours, what about this. The farm where we get our chicken carcasses, there's a bloke works 75 hours every week, he works Mon to Sat and he says "I get Sundays off, well except for nipping in for two hours to feed up" He nearly bloody lives there and every time we go to pick some chicken up, he's ALWAYS smiling, he just must love having his hand up a chicken's arse.
