re: Colorado School District Begins 4-Day School Week

Read about the reason why this is being done:
This district has the lowest teacher pay in the entire Denver area, leading to lots of turnover and low quality
The district has a much lower than average tax collection on a per student basis. The budget was in the red and voters did not pass a tax increase, so cuts had to be made.

You get what you pay for. I'm sure the teachers would have preferred a raise over having extended work days. In the end people are going to end up paying a lot more in child care than they would have if the tax had passed.
