"The union says the school district suffers a dire shortage of such personnel, with so few nurses that each is assigned to five schools. The union is also insisting on a higher wage floor for school clerks, teaching assistants and others, two-thirds of whose wages, it says, are so low that their children qualify for free and reduced-price school lunches under poverty guidelines. Members of a separate union, Service Employees International Union (SEIU) Local 73, representing security guards, janitors and special education aides, have already authorized a strike of their own, set to begin as early as Oct. 17."

I don't get the feeling that your union members are shaking down the school districts things is true to be honest, but I'd be interested if you have any citations. Your comment history is not encouraging though.
