This story takes place in Baltimore, Maryland. It actually involves a charter school. You see, the law in Maryland requires that charter school teachers be part of the union in their school district. That was their first mistake.
So this charter school, the KIPP Ujima Village Academy starts doing really well. Students at the school are outperforming students at the local government schools. One reason may be that the teachers at the KIPP Ujima Village Academy put in longer hours than their government school counterparts. KIPP teachers work nine hours and 15 minutes a day, as well as every other Saturday. Local government school teachers are only required to work seven hours and five minutes a day. And you can forget about weekends.
This is where the local union steps in and says "Hey, wait a minute. Teachers at this charter school are working longer hours than other unionized teachers at the government schools." The solution? The Baltimore Teachers Union says that this charter school must pay its teachers 33% more than other government school teachers. The charter school says ... screw you, we have a budget to meet (there's a concept no government hack would understand). So now, one of Baltimore's most successful schools is laying off staff and shortening its school day. They are doing this in order to please the teachers unions.
Oh wait ... you thought that teachers unions are there to enhance the education of your child? And just what planet did you say you are from?
