Talks began this week between the de Blasio administration and city unions over labor contracts for 300,000 municipal workers.

It was night and day compared to the Bloomberg era.

“I heard more worthwhile proposals in the first 45 minutes than I heard the previous three years,” Harry Nespoli, chairman of the Municipal Labor Committee, said.

“It’s refreshing to have negotiations where both sides respect each other and are willing to listen,” teachers union president Michael Mulgrew said.

Nespoli and Mulgrew know the cardinal rule of bargaining: when you want to make a deal, you do; when you don’t want to make a deal, you don’t.

In this case, both sides want one. City workers have not had a raise in three years; for teachers and nurses, it’s been five years.
