Over 1,000 contract workers – security officers, baggage handlers and wheelchair attendants – at both JFK and LaGuardia airports in New York have voted unanimously to strike.

Workers voted on Monday night to authorized a strike that would begin on Wednesday night at 10p.m..

The strike is aimed specifically at Aviation Safeguards, a company said to be a subcontractor for Delta Air Lines, while others apparently work for British Airways and United.

“While the airlines have been making record profits and the Port Authority has approved billions of dollars to modernize LaGuardia airport, the airport workers who make these profits possible are struggling to survive,” said a news release from SEIU 32BJ.

The union suggested that contractors have been mistreated and wage concerns ignored. They are demanding almost a 50% wage increase.

The contract workers will walk off the job at JFK’s Terminal 7, home to British Airways, United Airlines and Cathay Pacific Airways, at 10 p.m. The strike will continue through July 23 at JFK and LaGuardia, said Amity Paye, a spokeswoman for Service Employees International Union’s Local 32BJ.
