I like seeing an article that gets to the "real" level of the issues in Wisconsin. Some news sources lead you to believe it's all about health care and pensions, even though the teacher's union have said they would make changes to accommodate the budgetary issues.
This article talks about what would happen at the district level if teachers lose collective bargaining rights. Even some districts are not interested in teachers losing these rights. There are benefits for both the district and the teachers.
