NEW YORK — Fast-food workers in New York State would see a super-sized raise under a plan to phase in a $15 minimum wage — the first time a state has singled out a particular industry for such an increase.
The hike, approved Wednesday by the state Wage Board, would increase gradually over three years in New York City and six years for the rest of the state. It would apply to employees at any fast-food restaurant with 30 or more locations, aiding an estimated 200,000 workers.
‘‘You cannot live and support a family on $18,000 a year in the state of New York,’’ Governor Andrew Cuomo, a Democrat whose administration is expected to approve the increase, said at a Manhattan rally celebrating the proposal.
“This is just the beginning. We will not stop until we reach true economic justice,’’ he said.
San Francisco, Seattle, and Los Angeles approved gradual increases to $15 an hour, and the University of California system said Wednesday it will raise its minimum to $15 for all hourly workers.
With a large concentration of low-wage workers, the fast-food industry has become a popular target for labor activists who say chain restaurants have not kept up with the cost of living. Fast-food employees have emerged as a political force in New York and around the nation.
‘‘If I made $15, I could pay my rent on time, I could put food on the table, I could hold my head up,’’ said Rebecca Cornick, 60, a grandmother who makes $9 an hour at a Brooklyn Wendy’s. ‘‘We have worked so hard to make this happen.’’
Restaurant owners, however, have warned that higher wages will force them to raise menu prices, cut employee hours, and potentially hire fewer workers.
David Sutz, who along with his partners owns four Burger Kings in Westchester and Dutchess counties, said many owners may look to automation to replace workers to avoid the higher labor costs.
‘‘We’re being singled out for an unknown reason,’’ Sutz said of the increase. ‘‘Unfortunately, I can turn one of my registers into a kiosk and eliminate a position,’’ he said. ‘‘Labor is your second most expensive cost in this industry after the product.’’
Franchise owners are considering whether they could fight the increase in court. Carolyn Richmond, an attorney with Fox Rothschild LLP in New York City, said she cannot see a legal justification for focusing on a single industry.
‘‘This is certainly ripe for challenge,’’ said Richmond, who represents many hospitality businesses including fast-food companies. ‘‘It’s what legally we call ‘arbitrary and capricious.’’’
The fast-food industry employs a greater number of minimum-wage workers than other sectors, according to Michael Reich, a University of California Berkeley economics professor who has studied the minimum wage.
Entry-level fast-food workers make an average of $16,920 a year, according to New York State labor statistics. They are twice as likely to receive public assistance. Cuomo said the annual cost of that assistance to taxpayers is $700 million in New York State.
‘‘It accounts for more low-wage employment than any other,’’ Reich said of the industry. ‘‘If you’re going to pick one sector, it’s a strategic one.’’
The increase now goes to Cuomo’s labor commissioner for a final authorization. It does not require legislative approval.
