More than 2,000 unionized hotel employees staged a surprise strike across the province on Friday.
The strike affected 22 hotels in Montreal, Sherbrooke and Quebec City.
The employees, who are affiliated with the CSN labour federation, held a similar 24-hour walk-out on Aug. 8.
The walk-out is part of a campaign of rotating surprise strikes to speed up contract talks. Negotiations that began in April between hotel owners and the union have stalled.
The hotel employees want a 36 per cent pay increase over four years and an end to the use of employment agencies, among other demands.
Hotel managers have said that the union is asking for a lot and argued that working conditions in the industry are already good, but they also said they were willing to negotiate.
Workers were picketing in front of some hotels on Friday, including the Hilton in Quebec City. In a news release, they said they would hold a press conference in front of the Hyatt Place Montréal at 10 a.m. on Friday.
