Now that the ball is rolling on a $15 minimum wage, the labor movement needs to look further. I'm of the mind that we need to do away with the 40 hour work week.
We should fight for $20/hr, 30 hrs a week. that will get you the same weekly rate as $15 at 40 hrs. Overtime pay will kick in at 30 hours worked, with time and a half equaling $30/hr at minimum wage. Part time employees will be anyone working 20 hours or fewer, full time is anyone above that
