Airport workers filed 14 class action lawsuits Wednesday, claiming wage theft against their employers.
They say they aren't being paid the $15 dollar minimum wage in SeaTac, which went into effect in 2014.
Their lawyers estimate the workers are owed, on average, $20,000 in back-pay and penalties.
Duncan Turner is the lead counsel on the lawsuits, filed in King County Superior Court.
He says that many of the plaintiffs are immigrants, and they work as baggage handlers, rental car staff, janitors, and plane refuelers at Sea-Tac Aiport.
