About 10,000 hotel workers began a multiday strike Sunday in several U.S. cities after contract talks with Marriott International, Hilton Worldwide, and Hyatt Hotels stalled, the UNITE HERE union said.
The strike is affecting 25 hotels in eight cities, including Boston, San Francisco, and Honolulu.
Workers are demanding higher wages and a return to staffing levels seen before the COVID-19 pandemic.
About 15,000 workers have authorized strikes in 12 markets, with potential actions in Baltimore, New Haven, Oakland, and Providence.
The union warns that strikes could start in these cities at any time.
In Baltimore, housekeepers are seeking a wage increase to $20 per hour from the current $16.20.
In Boston, where housekeepers earn $28 per hour, the union is pushing for a $10 per hour raise over the next four years.
Hilton and Hyatt have expressed their commitment to reaching a fair agreement with the union.
The strike is part of broader negotiations involving 40,000 UNITE HERE hotel workers across 20 cities, with contracts set to expire this year.
