At the headline itself: only literally. For example, I (and many others in Canada) work graveyard. I only have to work 4 days a week (which is fantastic), and it's apparently echoed in this legislation as it "...limits the maximum workweek to 48 hours". Graveyard can limit ones health, but I think it gets a bad rap, and could wax poetic about other reasons I prefer it.
