The culinary and bartender unions announced Sunday that they struck a tentative five-year deal with the Golden Gate and will not picket there as planned.
On Saturday, the unions announced similar deals with four other downtown casinos: Four Queens, Binion's, Plaza and Las Vegas Club.
Hundreds of restaurant workers, hotel housekeepers, cocktail servers, bartenders and others had been scheduled to go on strike at 5 a.m. Sunday had agreements not been reached.
The settlements follow earlier deals with other downtown casinos.
Workers will vote whether to ratify the contracts next week.
Among other provisions, the agreements call for raises and keep employees' health care costs from increasing.
