Mulgrew boasts of victories in new teachers union contract

Mayor de Blasio got schooled with the new, nine-year teachers contract, union boss Mike Mulgrew is telling his rank-and-file.

“Health-care benefits preserved with no additional costs to members,” Mulgrew’s office said in a summary of the deal sent out to members of his United Federation of Teachers union.

Mulgrew took credit for securing retroactive pay that will be awarded in lump sums through October 2020.

“Be assured that all members will receive every penny that they have earned since Nov. 1, 2009,” he said.

But teachers noted that salary raises, a total of 10 percent over a seven-year period, will just barely keep up with the rate of inflation.

“If the best we can do is worsen conditions for our brother and sister unionists, we’re not doing our jobs very well at all,” said Francis Lewis HS teacher Arthur Goldstein.
