Security officers at John F. Kennedy Airport are threatening to walk off the job this month.

According to an AP report, the security officers say they want better training and equipment.

A strike-authorization vote is set for Thursday or Friday. If approved, they could walk out on Dec. 20, the report says.

The 300 security officers direct traffic in front of terminals and check tarmac gates to make sure they're secure, among other duties, the report says, and they work for two different companies, Air Serve and Global Elite Group.

The workers also filed complaints with the TSA, saying job conditions resulted in security lapses. According to the Wall Street Journal, the agency said an investigation didn't reveal any regulatory violations
