More than 100 workers at the Hyatt Regency Greenwich walked off the job Sunday morning.
Hotel workers, who are also members Local 217 - UNITE HERE, took to the sidewalk at the hotel entrance with bullhorns, drums and signs that read, "One job should be enough."
The union has been in the midst of contract negotiations for months and have not reached a deal.
The strike comes after the union's previous contract expired, Aug. 31.
Joshua Stanley, a chief negotiator for the union, said workers are at their breaking point and the strike was necessary.
"I think they're doing an amazing job and that courage is through the roof. I think this is a truly inspiring action that they're pulling off and couldn't be happier. Prouderto be part of our union," Stanely said.
Michael D'Angelo, Head of Labor Relations for Americas, Hyatt said in a statement:
"Our colleagues are the heart of our business, and Hyatt has a long history of cooperation with the unions that represent our employees, including UNITE HERE. We are disappointed that UNITE HERE has chosen to strike while Hyatt remains willing to negotiate. We look forward to continuing to negotiate fair contracts and recognize the contributions of Hyatt employees.
Hyatt hotels have contingency plans in place to minimize impact on hotel operations related to potential strike activity."
