Union members from Detroit’s three casinos overwhelmingly voted to authorize a strike if necessary, the Detroit Casino Council announced Friday.

The vote with 99% approval came as the union negotiates for higher wages at MGM Grand Detroit, Hollywood at Greektown and MotorCity casinos. The DCC said it could call for strikes as early as mid-October when contracts expire.

Workers casted their votes at the Teamsters Hall from 7 a.m. through 9 p.m. Friday. The results were released shortly after the polls closed.

In September 2020, following the COVID-19 shutdowns, the DCC said it agreed to a three-year contract extension with minimal wage increases “to help their employers get back on their feet.”
