Althouse linked. Thanks!
On a related note, we received a notice last week about a shortened day for school on Monday for a “necessary amendment” to the school schedule. My husband called the school district today to find out what the “necessary amendment” is. Turns out it’s for a union meeting. Our children have to lose part of their school day, interrupting their education, so the union can meet with teachers and staff. Apparently this is one of the many little work rules in the union contract with the school district. He has more here.
