A New York City union representing over a thousand workers at JFK International and LaGuardia Tuesday announced plans to strike for higher wages and benefits.

“On Wednesday July 22 at 10 p.m. airport workers for Delta’s subcontractor Aviation Safeguards at both JFK and LaGuardia will launch a strike to protest their employer’s repeated, illegal threats,” a press release from Local 32BJ of the Service Employee International Union stated.
