LOS ANGELES (CBSLA.com) — As labor negotiations between trash truck drivers and the city of Los Angeles continues, trash pick-up service will be delayed a second day with just about a fifth of sanitation drivers not showing up for work.

The Los Angeles Bureau of Sanitation reported Wednesday that only about 40 percent of the city’s 500 sanitation workers reported for duty. That number rose to about 80 percent Thursday.

The remaining workers will continue to focus on picking up black waste bins containing solid waste, sanitation officials said in a statement. Bins for recyclables ad green waste should be picked up by Saturday evening, officials said.

Residents are being asked to leave out their bins until they have been collected, and bulky item pickups also are being rescheduled.

SEIU Local 721 spokeswoman Coral Itzcalli said that the trash driver work stoppage is “not a union-sanctioned activity.”

The union represents about 10,000 Los Angeles city workers, including trash truck drivers, tree-trimmers and street repair crews.

Its members began voting on Tuesday night to decide whether they will go on strike, Itzcalli said, but she declined to say when voting would be completed.
