On Tuesday in New York, the United Federation of Teachers expects to formalize a contract with teachers at Green Dot New York Charter School in the Bronx, a high school run by Green Dot, a nonprofit group that operates charter schools. Ten other New York charter schools are unionized.

Education Secretary Arne Duncan made a point of talking about unions in a speech Monday in Washington to a national charter school conference.
