But isn't 20 hours/week or 40 hours/week a negotiated agreement when you got hired? If you want 20 hours/week, get paid less and stop whining about companies should pay more for less amount of mandatory work hours. The discussion should have been more like employees should have more options on choosing how many mandatory work hours they are willing to offer a week when signing agreement with a company. I am utterly surprised, though not all people here are from the capitalism driven world but majorities are talking like they are living in socialist world.
