Jim Callaghan, a veteran writer for the United Federation of Teachers, just got canned for ... trying to unionize the powerful organization's own workers!
Jim Callaghan, a veteran writer for the teachers union, told The Post he was booted from his $100,000-a-year job just two months after he informed UFT President Michael Mulgrew that he was trying to unionize some of his co-workers.
"I was fired for trying to start a union at the UFT," said a dumbfounded Callaghan, who worked for the union's newsletter and as a speechwriter for union leaders for the past 13 years.
Callaghan said he personally told Mulgrew on June 9 about his intention to try to organize nonunionized workers at UFT headquarters.
"I told him I want to have the same rights that teachers have," said Callaghan, 63, of Staten Island. "He told me he didn't want that, that he wanted to be able to fire whoever he wanted to."
