Neither of us could come to an agreement due to the fact that we we're both right and wrong at the same time, therefore confusing the s**t out of ourselves.
It wasn't until after I knocked off that my head stopped hurting and I could clearly see the answer.
I'm posting the problem here, just so that I could make other people suffer, as we did
For truck drivers, the law states that over a 7 day period I can only work for a maximum of 72 hours and must have a continuous 24hr break.
Shifts are like so:
Night shift one week, day shift the next, night shift the week after that and so on.
Night shift = 4pm - 4am Sun, Mon, Tue, Wed, Thu, Fri
Day shift = 4am - 4pm Sun, Mon, Tue, Wed, Thu, Fri, Sat
No work between 4pm to 4am starting from Saturday afternoon
My argument was that I work 72hrs a week and have a continuous 24hr break over 7 days.
His argument was that for day shift, I work for 84hrs and do not have a continuous 24hr break over 7 days. Therefore exceeding the legal working hours.
What do you see?? (Using your head only, neither of us had any 'visual aids' at the time)
