France: The best intentioned legislation can have unintended consequences
To understand why let's say someone was earning $10 an hour and working for 35 hours a week, making $350 a week. Further assume that they pay 50% of their income in taxes so they get to keep $175.
Now imagine that the employee and firm come to a new arrangement. The employee will start sleeping at the office and the firm will consider this office sleeping time to be work. The employee will now be paid for working 60 hours a week. The firm, however, will also cut the worker's salary to $5 an hour. The firm now pays $5(60)=$300 a week. This is less than before so the firm is better off. The worker, however, is also better off. . . . .
