Members of the New York City Patrolmen's Benevolent Association followed Mayor Bill de Blasio during his morning routine Tuesday to protest their pay and contract negotiations.

The displeasure felt by some members of the NYPD comes as many of them are working without a contract. Dozens of PBA members were outside Gracie Mansion to greet the mayor as he began his day.

They followed de Blasio to the Prospect Park YMCA in Park Slope where he usually exercises.

The union says it has been negotiating for two years. PBA President Patrick Lynch says the situation affects families of union members the most.

"We're 34 percent behind the police officers that surround us," Lynch says. "We're losing our fully trained officers...because they cannot afford to live in the city that we protect each and every day."

De Blasio declined to comment upon finishing his workout. His office later released a statement that read: "Under this mayor, crime has fallen to record lows, 1,300 more cops are on the street and we've invested $320 million more in officer safety and equipment. We are willing to talk about this every day - at the gym or anywhere else."

The pay and contract protest took place on the same day NYPD Commissioner Bill Bratton announced his resignation.
