Chris and I discussed this, and we concluded that the incident doesn't just show why charter schools need unions -- it shows why people need unions. Disclosure: both Chris and I have worked for unions. But the point is, when you have a union contract, there are clear and fair channels for being fired.
The Chalkboard doesn't think that "all charters need unions just because of one dude who seems to be on an ego trip." I disagree. Charter school leaders tend to be very strong personalities who decide to open schools because they think they know how best to run a school. For a lot of these leaders, not wanting to have unionized teachers is as much about cost saving as it is about not having another entity that teachers can report to. I know people like this, and my sources tell me that the WCS school leaders are of that type.
Chris says that this incident is why mandatory unions in charter schools are necessary. He says that unless businesses (like schools) are forced to have unions, you are always going to have things like this that are just not reported. The state should say you have to have unions, and if the teachers in a charter school want to negotiate their own contract they should be able to do that.
If the school's charter is revoked, it's going to be really bad for a lot of kids. I know that's what everyone says whenever this happens, but still. Also, there is a serious dearth of charter high schools in New York City. There are a lot of other good options for high schoolers here, but at this late date these kids are going to end up at their crappy neighborhood schools.
