A coke-snorting ex-labor leader was sentenced yesterday to 11 years behind bars after admitting to selling out thousands of rank-and-file union members so he could live the high life.

Michael Forde, former chief of the powerful District Council of Carpenters, begged forgiveness shortly before being sentenced in Manhattan federal court for spearheading a 15-year corruption scheme in which he pocketed hundreds of thousands of dollars in bribes.

In exchange, Forde let corrupt contractors hire illegal aliens, costing members more than $18 million in union benefits.

Forde “spent most of his time . . . partying, golfing, dining and getting high on cocaine” with cronies taken along at the union’s expense — including his own “personal cocaine supplier,” the papers say.
