The Super Bowl is set to be held in Las Vegas on Feb. 11 and two threatened strikes in the city could alter the plans of many heading to Sin City for the event. Last week, Culinary and Bartenders Union members at 21 Strip and downtown casinos announced a strike date for Feb. 2 if a new contract can’t be reached.

That would affect more than 5,500 workers and now another union is also threatening a work stoppage in Las Vegas. On Friday, hundreds of drivers and mechanics with the Regional Transportation Commission of Southern Nevada (RTC) rejected a proposal from Transdev, the firm managing route operations for the commission.

RTC driver Dennis Hennessy told KVVU if workers decide to walk off the job, the strike would affect Super Bowl activities. He said workers are seeking better pay, benefits, and job protections.

Transdev says a strike would be violating the law as both parties are currently operating under a valid work agreement as negotiations continue.

“Transdev has not received a formal strike notification from the ATU Local 1637,” the company noted in a statement. “Both organizations are under a Transition Agreement that requires a 30-day written notice from the union to legally strike. As of today, Transdev remains at the table bargaining in good faith with our partners at ATU.

“Both parties are operating under a valid agreement, so any violation of this agreement would be an unlawful act. It is Transdev’s expectation that the ATU will honor the agreement and deliver uninterrupted service to the public. We remain committed to providing safe and reliable service to our community.”
