A prospective wage employment class action lawsuit has been filed against about 20 Denny’s restaurants in Connecticut for allegedly failing to pay its servers at least the minimum wage for non-service-related duties.

The lawsuit, which was filed Nov. 19 on behalf of current employee Valarie Nettleton, alleges C&L Diners LLC—owners of most of the state’s Denny’s franchises—routinely failed to separate its servers’ non-service and service duties. The complaint alleges the 48-year-old Nettleton, who began working at the Westbrook Denny’s in November 2016, would be assigned non-service work, usually prior to and after her shift, but also during her shift. The franchise, the complaint alleges, is in violation of the state’s Minimum Wage Act.
