NEW YORK (Reuters) – About 1,070 hotel workers in the U.S. cities of Boston and Greenwich are on strike after contract talks with hotel operators Marriott International (NASDAQ:), Hilton Worldwide and Hyatt Hotels (NYSE:) stalled, the Unite Here union said on Sunday.

The union said the strikes in Boston and Greenwich would last three days, adding that more hotel workers in various U.S. cities were expected to walk off the job over the Labor Day weekend.

Unite Here, an organization representing hotel, casino and airport workers in the United States and Canada, said frustrated workers could strike in major tourist destinations including San Francisco and Seattle as they seek to reach agreements with hotel operators on wages and to reverse pandemic-induced job cuts.

“Strikes have also been approved and can begin at any time in Baltimore, Honolulu, Kauai, New Haven, Oakland, Providence, San Diego, San Francisco, San Jose and Seattle,” Unite Here said in a statement.

A total of 40,000 Unite Here hotel workers in more than 20 cities are working under contracts that expire this year. About 15,000 of those workers have called strikes in 12 markets from Boston to Honolulu.

Since May, employees have been negotiating recent four-year contracts.

“We are striking because the hospitality industry has lost its way,” said Gwen Mills, president of Unite Here.

“We will not accept a ‘new normal’ where hospitality businesses profit from reducing what they offer to guests and abandoning their commitments to employees,” Mills added.

Unite Here workers won record contracts in 2023 in Los Angeles after mass walkouts and in Detroit after a 47-day strike.

In Las Vegas, casino operators MGM, Caesars (NASDAQ:) and Wynn Resorts reached an agreement in November to avert a strike by 40,000 hospitality workers just days before a deadline that would have paralyzed the Las Vegas Strip.
