Volunteerism

Emphasis added.

The school-district leadership finds itself caught between the volunteers and the union, seeking to pacify both parents and the CSEA. Meanwhile, important positions lost to budget cuts that volunteers could handle remain unfilled. Deputy Superintendent Steve Bolman is left to quote from the union contract and labor law: "It's not policy, this is law. [Volunteers] can't do work 'usually, ordinarily or regularly done by classified employees.'" For her part, Kruusmagi sounds a little sketchier on the legalities: "I can't cite the exact thing," she says, "but there are state rules. I believe it's in [education] code that volunteers are not allowed at schools."
