Valet and parking attendants at Rhode Island's Twin River casino are on strike over stalled contract negotiations.
Some 40 employees affiliated with the Teamsters Local 251 labor union walked off their jobs at the Lincoln facility Friday afternoon.
The Providence Journal reports the workers marched along the road leading to the casino and displayed a 15-foot inflatable pig smoking a cigar with the tag line "corporate greed."
Labor union officials told the newspaper the workers would be picketing through Sunday morning and that other casino unions are honoring the demonstration.
The casino said in a statement it was disappointed by the union's decision but had made other arrangements for valet services during the work stoppage. It also noted it has been able to reach agreements with other casino worker unions.
