MASHANTUCKET, Conn. -- Workers are scheduled to demonstrate on Saturday and Sunday in protest against the weekend opening of a new MGM Grand casino at Foxwoods.

Attorney General Dick Blumenthal's office facilitated an agreement between the UAW, the Department of Transportation (DOT) and state police regarding the protests after DOT initially denied UAW's permit requests, according to a UAW statement.

The rallies will be held from 12 p.m. to 11 p.m. Saturday and 9 a.m. to 12 p.m. Sunday at Route 2 outside of Foxwoods.

UAW members and labor and community allies are demonstrating because of management's refusal to bargain a union contract, according to a UAW statement. Working conditions have worsened since casino dealers voted to unionize in November 2007, workers said.

"We're glad we could reach an agreement on this event that works for everyone," said Bob Madore, director of UAW Region 9A, in a statement. "We're going to be there, we protected our first amendment rights, and we are confident we will get our message out."

Some stars also will be in attendance for the grand opening, with Michael Douglas, Catherine Zeta Jones, Jamie-Lynn Sigler, Jenny McCarthy and Salt 'n Pepa among those slated to walk the red carpet.

The red-carpet walk, which takes place at 240 MGM Grand Drive in Mashantucket, begins at 7 p.m. Saturday, followed by an evening of performances featuring John Mayer, Josh Groban and additional Grammy Award-winning artists. Sean "Diddy" Combs is slated to host the after party at Shrine Nightclub.
