Teamsters Local 992 won the right to represent three employees at Yellow Freight Systems Inc., the union said Monday.
The workers, all clerks, were granted recognition after they were checked to see if they had signed cards authorizing union representation, said Teamsters organizer Tom Krause. A card-check is an alternative to an election on whether employees want union representation, he said.
"The employees are to be commended for their courage and their integrity," he said.
The Teamsters also represent about 28 other Yellow Freight employees, Krause said.
