Teachers and staff at the Multi-Cultural Academy Charter School in North Philadelphia have voted to be represented by an affiliate of the American Federation of Teachers Pennsylvania.

In balloting Friday, the school's 25 teachers, counselors, and office and support staff voted for representation by the Alliance of Charter School Employees, an affiliate of AFT Pennsylvania that represents employees of four other charter schools in the city, the union announced.

The decision comes several weeks after Multi-Cultural's board of trustees voted to remove Vuong Thuy, the school's founding chief executive, as top administrator amid allegations that charter money was being diverted to cover his legal bills stemming from a federal probe and a state ethics investigation. - Martha Woodall
