FanDuel, which operates the FD Sportsbook in conjunction with MotorCity, told CNBC it will be closed with the exception of a non-union MCC employee managing the cash at the counter for patrons needing to cash in tickets, which keeps with Michigan regulatory requirements.

The Hollywood Casino at Greektown said in a statement to CNBC, "We are disappointed by the decision of the Detroit Casino Council as we have made generous, progressive settlement offers that position our team members and business for sustainable success." The management says it will remain open for business.

Matt Buckley, president and COO of MGM's Midwest Group, sent a letter to employees of MGM Grand Detroit that made clear the company also intends to keep the property open and running.

The Detroit Casino Council argues casino workers agreed to a three-year contract during the pressure-packed earlier days of the Covid-19 pandemic. The deal, which has now expired, included 3% wage increases even as the cost of living has surged 20% amid , according to the union.

MGM CEO Bill Hornbuckle told CNBC during a keynote presentation at the Global Gaming Expo last week that he and top leadership from the other casinos are involved in intense negotiations. But he said the unions in Las Vegas are influenced by other attention-grabbing strikes.

"It doesn't help when UAW in Detroit is asking for 40%. I mean, that's a top line that's hard to ignore," Hornbuckle said at the time.

And so I think that's what's relevant."
