A move to create a union at one of the city's leading charter schools may turn into a protracted battle, as the deadline passed on Thursday for the school, KIPP AMP in Crown Heights, Brooklyn, to voluntarily recognize the union.
The United Federation of Teachers, which is seeking to represent the teachers, must now file for recognition with the state's Public Employment Relations Board, which will most likely give the school's administration several days to respond.
David Levin -- a founder of the national network that operates the schools, the Knowledge Is Power Program, and the superintendent of its four New York City schools (another will open this summer) -- said that the administration would "respect and follow the state process," but did not specify what, if any, challenges it would raise with the labor board.
"For the past 15 years, it has been the ability of everyone to work together, and to do that with flexibility has been the key to our success," Mr. Levin said in an interview on Thursday. "We were created as an alternative to the public schools, and we need to be committed to and maintain our work and focus on results."
