LAS VEGAS >> A union representing hospitality workers says it has reached a tentative agreement with six more hotel-casinos in downtown Las Vegas and called off a strike deadline for another.

The agreements averted a walkout threat this morning at several near-Strip and downtown properties as the city kicks off Super Bowl week.

The Culinary Workers Union announced Saturday that it had reached a tentative five-year contract with the Golden Nugget, Binion’s, Four Queens, Fremont and Main Street that covers about 1,000 workers.

The union reached a tentative agreement Sunday with Downtown Grand, which represents about 200 workers.

The culinary and an associated bartenders union are being given more time to reach an agreement with Virgin Las Vegas, an off-Strip resort.

The Las Vegas Strip’s three largest employers — MGM Resorts International, Caesar Entertainment and Wynn Resorts — reached deals late last year with union that covered 40,000 members, narrowly averting a historic strike.

The union then turned its attention to winning the same contract terms for workers at other hotel-casinos in Las Vegas.

Since early January, the union had settled negotiations with most of those properties including Circus Circus, Sahara Las Vegas, the Strat, Circa Resort and the El Cortez.

But after hitting a snag in negotiations with some of the remaining casinos, the union announced last week that it would go on strike if tentative contracts weren’t in place by 5 a.m. Monday for downtown casino workers at properties that hadn’t reached agreements.

The NFL’s 58th championship game is expected to bring some 330,000 people to Las Vegas this week, according to the Las Vegas Convention and Visitors Authority.

The Culinary Union is the largest in Nevada with about 60,000 members statewide. It negotiates on behalf of its members for five-year contracts.
