As many as 1000 Service Employees International Union (SEIU) workers at Los Angeles International Airport (LAX) are considering going on strike on Thanksgiving eve in what is the busiest travel day of the year.

Andrew Gross-Gaitan, the director of the Southern California Airports Division of SEIU, said the protest would be in response to an LAX contractor that failed to comply with the city’s Living Wage Ordinance. 

“When people’s lives are on the line, their family members are on the line, they’re not going to be able to enjoy their Thanksgiving," Gross-Gaitan told KNX 1070 Newsradio. “This is really a critical moment for thousands of workers.”

An estimated 1.8 million passengers are expected to travel through LAX over Thanksgiving weekend, and the potential strike would cause chaos at the airport.
