The American Federation of Teachers said that they are against pension practices like end-of-career spiking and double-dipping. These measures increase the amount of the pension that workers receive. The teachers' unions have received criticism for not doing enough to address the problem. The AFT said that it supports well-funded pensions for its members, and that it will continue to bargain for retirement coverage and shared responsibility for pensions.
