No, it’s not about the kids; it’s about adults in the system.
A Detroit News blog exposes the problem very nicely.
Furthermore, the blogger points out an outstanding example of how privatizing custodial services saved a Michigan school district big money as expenses dropped from $17–20 per hour to $9-10 per hour. Instead of the district’s schools being cleaned only every other day, they now get daily cleaning. In addition, the district will save $5 million over the next five years.
Somehow, the Michigan Education Association even tried to make this out as something bad for schools.
