NEWARK - Hundreds of protesters gathered at Newark Liberty International Airport Monday to call for workers’ rights.

The protesters included baggage claim handlers, TSA employees and others, including some state leaders. They are calling for a pay increase to $15 an hour, as well as increased health benefits and better working conditions.

The workers chanted “No justice, no peace,” and waved signs as they marched from airport terminal to airport terminal.

Twelve of the protesters were arrested as they staged civil disobedience by sitting in the road to block traffic.

The airport workers’ wage did increase last year, to $10.10 an hour. The Board of Commissioners of the Port Authority is reportedly split on the issue of whether or not to raise the wage again.

Similar protests were held at airports in Boston, Chicago, New York City, Philadelphia, Miami, Seattle, Portland and Washington, D.C.
