There is so much wrong with the OP and the DUmpmonkey poo-flinging I don't even know where to begin, but let me start somewhere...
First, civil servant unions such as NEA, SEIU, etc, will NEVER agree to six-day workweeks without SERIOUS salary enhancements (that's payraises, DUmmies).
In a day and age when most states and towns are looking to CUT, not expand, forcing workers, teachers (and yes, students) to come in will increase costs to the government even if you don't raise salaries one dime.
I'd love to find ONE union which is agreeing to foist a six-day workweek on their members without some serious giveback from the companies asking for them. Were that the case the rank-and-file would almost break the sound barrier in getting that union decertified.
