I also can't stand the fact that smokers can take unlimited 'breaks' whenever they please just to come back stinking up an entire room with their smoke.
That feels like a workplace problem. Why would a workplace give them unlimited breaks? And why would nonsmokers not be allowed comparable breaks? This feels odd to me. My recent jobs have been ones where nobody is micromanaging my time, so anyone can take whatever breaks they want. As long as productivity doesn't obviously suffer, nobody cares. My past jobs in retail didn't allow smokers to take extra breaks. They'd get the same breaks as everyone else (for an 8 hour shift, that meant a 30 min lunch and 2 x 15 min coffee breaks).
