Seventy percent of you think smoking isn't a work-related issue [1] and that employees' private habits shouldn't be the business of their employers. The discussion about company policies trying to intervene in the smoking habits of workers is a far cry from the smoke-filled office on Mad Men [2]. Cigarettes are permanent fixtures in the hands of employees on the show: They smoke in personal offices, during hallway conversations, and in meetings no matter how long or short.

Today's workplaces aren't exactly welcoming of smoking, particularly during work hours. The stigma around smoking has made it a habit employees keep to themselves, but there's no denying the scent of a recent cigarette. Do you know which co-workers smoke?
