More than 1,000 security officers, baggage handlers and wheelchair attendants plan to walk off the job for 24 hours at New York City's John F. Kennedy and La Guardia Airports, workers and union officials announced Tuesday.

The action has been brought by airport workers for Delta subcontractor Aviation Safeguards, said officials with Service Employees International Union Local 32BJ.

Workers said they will start walking off the job at 10 p.m. Wednesday and will picket and hold rallies at JFK and La Guardia airports throughout the 24-hour period.

Hector Figueroa, 32BJ's president, said the workers are attempting to form a recognized union and "have not yet won recognition of their bargaining status."

"They have expressed that they want 32BJ as their representative and obviously we support that," he said.

Craig Coy, chief executive officer of Command Security Corporation and its subsidiary Aviation Safeguards, said the company believes the workers haven't followed proper procedures to organize.

"Our view is the employees should have the legal right to choose rather than have it forced on them," he said.

In a statement, the Port Authority said it had taken significant steps in recent years to encourage wage and benefit increases for employees of airline contractors at its airports and "will work to avoid disruptions of airline operations at PA airports."

American Airlines Group Inc. said that it wasn't anticipating disruptions. A Delta Air Lines Inc. spokeswoman said the company "for now" will defer comment to the Port Authority.
