Management and unions representing salaried employees at Hilton hotels in Quebec City and Holiday Inn in Laval have reached a tentative agreement.

Michel Valiquette, spokesman for hotel unions with the CSN – the confederation of Quebec trade unions – said the agreements are on par with the demands of the unions in 35 different hotels.

This is the eighth round of negotiations orchestrated by the CSN, which said it improved working conditions for salaried workers in the hotel industry because of its bargaining procedures.

Valiquette said the "domino effect" caused by the unions in 35 hotels is proving to be a successful tactic in reaching agreements with the various administrations.

Hotel employees at the Hilton and the Holiday Inn will vote on the agreements, which would expire in 2016.

Workers at Château Cartier in Gatineau and the Quality Inn in Sherbrooke have accepted the offer. Five others still remain on the table.

Hotel workers are demanding better employment security and increased employer participation in their pension plans.

Some Montreal hotels have been dealing with similar issues.

Montreal's Hyatt Regency has been in conflict with employers since July 25, the Holiday Inn Select Sinomonde has been on lock-out since Aug. 5, Hotel Espresso locked out its staff on Aug. 16 and Maritime Hotel workers faced locked doors in late August.

The current negotiations involve 35 unions, representing some 5500 members who work in the hotel industry in various parts of the province.
