Teachers reach contract deal at Chicago charter schools

CHICAGO (AP) - Teachers at a network of charter schools in Chicago have reached a tentative contract agreement, averting a possible strike.

A union representing the teachers, counselors and support staff announced the two-year agreement late Thursday with ASPIRA schools. It's subject to a ratification vote.

The tentative agreement includes raises, trimming the school year without affecting educational time for students and increasing vacation time.

Charter chairman Fernando Grillo says in a statement that they "look forward building a strong future for ASPIRA."

Teachers at the four schools are represented by the Chicago Alliance of Charter Teachers and Staff, a branch of the American Federation of Teachers union. They've been negotiating for a new contract since last year and had voted to go on strike.
