Education Commissioner Bret Schundler isn’t buying it. He says he thinks less that 13,000 teachers will retire based on the new proposals by the governor for pension and benefits reform. The New Jersey Education Association said they thought over 30,000 teachers would leave as a result. Some of the changes being looked at in Trenton is calculating pensions based on the final five years of employment, and no longer the final three, and removing a nine percent increase teachers got in 2001.
