Two dancers at a Dartmouth strip club have sued the owner over back pay they say is owed to them and about 100 other workers. Lawyers for the dancers at Kings Inn say the women were denied minimum wage and other labor protections, even though they earned up to $900 per night. The lawyers told The Standard-Times of New Bedford that the dancers were employees of the club, but were incorrectly classified as contractors. They say that if more Kings Inn employees sign on, it could lead to millions of dollars in back pay. A lawyer for the club said the dancers were independent contractors who paid fees to use the club, a common practice in the industry. He says the owner plans to fight the suit in court.
