Personally, I don't work a standard Mon-Friday week anyway, I'm a University student so my time is split about evenly between studying/partying/sleeping/online work. Obviously this means that I'll sometimes work on a Sunday (with a nasty hangover I might add!!), but there'll also be plenty of days in the week where I don't do any work at all.
I work even sundays, whats wrong with that? But everybody should take time to rest, especially on weekends with family.
I don't work on Sunday, I'll spend my time between my online job and family, that's life suppose to be
