The concept is unfair, they're practically being rewarded for smoking.
For my case personally, it kinda works out nice. There's only 1 person I work with at a time, so whenever he goes out for his smoke break (which is literally at least once every hour, dude must smoke a pack a day) I just pull out my phone and chill. If he gets a break, I get a break.
Granted though, I have literally the easiest job in the world and half the time I'm just sitting there doing nothing so I can't really complain
