While a charter school in Chicago looks to form a union, the Illinois Network of Charter Schools wants to ensure other unions don’t impose.

Illinois law does not force a charter school to create a union, but does allow for the option among members. The Illinois Federation of Teachers touts the recent vote approving a union for the Passages Charter School in the city’s West Edgewater neighborhood. Workers voted to join the Alliance of Charter Teachers and Staff Local 4343. However, Andrew Broy, president of the Illinois Network of Charter Schools, has some concerns. Broy says there could be problems if the Chicago Teachers Union takes an interest in bargaining on behalf of charter school unions.

Broy says of the charter schools in Chicago, most have chosen to remain independent of creating a union and only two of the 15 charters outside of Chicago have a union.
