The Teamsters union said a group of American Red Cross workers who collect blood for the organization in Kansas have voted to join Teamsters Local 795 in Wichita.
According to a Teamsters news release, the Wichita bargaining unit will represent 91 workers.
The workers voted 64-13 to join the Teamsters, the release said.
The union said there are 18 Teamster local unions across the U.S. that represent Red Cross biomedical service workers. The newest members will be part of the Teamsters Public Services Division, which represents more than 260,000 union members.
