Eight hundred workers near Toronto have won the first Walmart warehouse union in Canada or the U.S. “Honestly I was pretty nervous at first because I didn’t want to lose my job,” said 29-year employee Rodolfo Pilozo, a member of “Team Red,” the organizing committee behind the September victory. The Walmart distribution center is in Mississauga, Ontario, an hour from the western New York border. Workers there began organizing last December to join Unifor, Canada’s largest private-sector union. Forty percent signed union cards over the summer.
