 In 2010 Rhee and the unions agreed on a new contract that offered 20 percent pay raises and bonuses of $20,000 to $30,000 for "strong student achievement," in exchange for weakened teachers' seniority protections and the end of teacher tenure for one year.Under this new agreement, Rhee fired 241 teachers, the vast majority of whom received poor evaluations, and put 737 additional school employees on notice.Rhee's style of reform created a great deal of controversy.
