The city's living wage ordinance, passed a decade ago, requires workers at companies that contract with Los Angeles be paid wages and benefits equal to $10.64 an hour.

The Save LA Jobs group opposes expanding the ordinance to hotels around Los Angeles International Airport that have no formal financial relationship with the city, The Los Angeles Times reported.

Many hotel workers already make the so-called living wage but airport-area hotels have resisted expanding the ordinance effort, in part because labor seeks to use the law to pressure the hotels to recognize an ongoing effort to organize their workers, the newspaper said.

Some hotels have suspended or fired employees involved in the organizing effort, the Times said.

The city clerk has 30 business days to verify the signatures. The City Council also must decide whether to rescind the ordinance or to schedule it for a citywide vote.

If the council chooses to put the issue on the ballot, the vote would be held no earlier than May, the newspaper said.
