New York City police union leaders filed a grievance this week after being told officers' July Fourth holiday pay would be delayed.

The Patrolmen's Benevolent Association said the delayed payments violate the union's contract and come as thousands of NYPD officers prepare to work long hours securing one of the city's busiest holiday weekends.

City officials under Mayor Zohran Mamdani informed union leaders Wednesday that officers' holiday paychecks would be issued during the third week of July instead of the second week, as has been customary, the New York Post reported.

PBA President Patrick Hendry blasted the move in a message to union members, calling it both a contractual violation and a slight against rank-and-file officers.

"This is not only a violation of our contractual rights. (It's) also an insult to PBA members who are working long hours in extreme heat to meet the extraordinary security demands of the upcoming holiday weekend," Hendry wrote, the Post reported.

The union filed a formal grievance Wednesday with the NYPD's Office of Labor Relations, a dispute that could ultimately proceed to arbitration if the issue is not resolved.

The PBA also took its complaint public on X.

"Our members are facing an incredible workload over the holiday weekend," the union posted. "The city absolutely should not be holding up their holiday pay. The PBA has filed a grievance, and the NYPD informs us that they're intervening with city payroll to correct the issue."

The NYPD, however, said the problem was not intentional and blamed an internal administrative mistake rather than a policy decision.

"This was an internal processing error, and we are working hard to address it immediately," the department said in a statement to the Post.

"We believe we will be able to fix it and ensure that everyone receives their holiday pay in the second paycheck of this month, as they so rightfully deserve."

The department added that "no one does more for this city than the cops, and the very least they deserve is timely pay for the work they have done."

Holiday pay varies by seniority, but entry-level officers are expected to receive nearly $2,800, according to the Post.

The dispute surfaced just as Mamdani and NYPD Commissioner Jessica Tisch announced extensive security plans for the holiday weekend.

Thousands of officers are scheduled to work 12-hour shifts covering major events, including the Fourth of July fireworks celebration, the International Naval and Aviation Review, and other high-profile gatherings, including the rumored two-day Taylor Swift and Travis Kelce wedding celebration at Madison Square Garden.

According to Hendry's email, officers also experienced a holiday pay delay in January shortly after Mamdani took office.

At that time, city officials cited payroll system updates tied to new tax requirements.

Hendry said the city has offered no such explanation for the latest delay, prompting the union's grievance as officers shoulder another demanding holiday assignment.
