I guess it depends on the company. Mine clearly expects us to work on 37.5 hours per week whether you work non stop from 9 to 4.30 or from 7 to 7 with many long breaks. And any overtime I do during the week makes my day at work on Friday that much shorter.
I guess the difference between the prohibition in the US and this bill, is that the alcohol prohibition banned it to everyone at once. People who were used to drinking or down right alcoholics had a strong incentive to obtain alcohol from somewhere, so there was a market for the underground moonshine producers. This bill isn’t targeting people who are already addicted to nicotine, but rather aims at preventing people developing the addiction in the first place, so I can imagine the market for underground tobacco growers or smugglers will be much smaller and less profitable. I am optimistic that this approach will be more successful than the 20s in America, but I guess we’ll have to wait and see.
