A labor union has won the right to represent several hundred employees who work for AirServ Corp., a Delta Air Lines subcontractor, at Minneapolis-St. Paul International Airport.

The Service Employees International Union (SEIU) Local 26 said Monday that the majority of about 600 AirServ workers at MSP signed cards supporting unionization.

They include baggage handlers, cabin cleaners, cart drivers, wheelchair agents, unaccompanied minor escorts, lavatory workers and water-service fillers.

The Minneapolis-based local will now negotiate a contract with the Atlanta-based firm on behalf of the workers, the majority of whom are East African.

No date has been set for contract negotiations.

AirServ could not be reached for comment Monday.

The union began organizing workers at the airport in 2013, holding numerous rallies and attending meetings of the Metropolitan Airports Commission.

In 2015, due to pressure from SEIU and other groups, the MAC increased pay at the airport to $1 an hour over the state minimum wage of $9 an hour and required employers to provide some paid sick time.

A neutral third party recently verified that a majority of workers at MSP signed cards supporting the union.

SEIU Local 26 represents some 6,000 workers in the Twin Cities metro area, including janitors, security officers and window cleaners.
