Where Did I Go Wrong?

In a defiant raspberry to the city Department of Education — and taxpayers — disgraced teacher Alan Rosenfeld, 66, won’t retire.

Deemed a danger to kids, the typing teacher with a $10 million real estate portfolio hasn’t been allowed in a classroom for more than a decade, but still collects $100,049 a year in city salary — plus health benefits, a growing pension nest egg, vacation and sick pay.

Mayor Bloomberg and Gov. Cuomo can call for better teacher evaluations until they’re blue-faced, but Rosenfeld and six peers with similar gigs costing about $650,000 a year in total salaries are untouchable. Under a system shackled by protections for tenured teachers, they can’t be fired, the DOE says.
