Some 1,000 Service Employees International Union workers will march on Century Boulevard on Wednesday afternoon - one of the busiest travel days of the year -- to bring attention to its dispute with LAX contractor Aviation Safeguards.
"Workers are being forced to take drastic action," said SEIU member Ernesto Guerrero. "It's not going to be a strike, but it's definitely going to be a major street action coming into the airport."
The union says the company illegally decertified the union and took away their healthcare. The company says workers voted to leave the union and that it has given workers a wage increase to compensate for its new healthcare policy.

Gas prices in Los Angeles are currently around $3.83 for a gallon of regular, almost a full dollar below last month's record. It's $3.79 in Orange County, $3.80 in the Inland Empire and $3.83 in Ventura County.

"It saves a bit and keeps my wife out of the mall on Black Friday, too," he said with a laugh.
