The city’s top labor negotiator turned to some familiar faces to help hammer out dozens of municipal contracts, by bringing on the consulting firm he founded.

Three months after Robert Linn was appointed labor commissioner, the city inked a $99,500 no-bid contract with Linn & Logan Consulting, Inc., founded by Linn in 1995.

He served as executive director until January’s appointment.

Linn got clearance from the Conflicts of Interest Board. Mayor de Blasio spokesman Phil Walzak said the urgency of contract talks precluded soliciting bids.
