Teachers at a Chicago charter school are now subject to private-sector labor laws, rather than state laws governing public workers. The move could impact how public schools are run down the road.
The ruling, made by the National Labor Relations Board last month, said the Chicago Math and Science Academy is a "private entity" and therefore covered under the federal law governing the private sector.
The decision overrules a vote taken by teachers last year to form a union in accordance with the Illinois Educational Labor Relations Act. At the time, two-thirds of teachers at the school approved the union and it became official under state law.
