HIBBING â The Teamsters Local 346 union called its third day of strike in a week on Thursday, sending about two dozen workers at the Aramark Uniform Services off the job after 10 months of negotiations over salary increases and what it considers overtime issues and unsafe labor practices. An Aramark spokesperson said there were no immediate disruptions, and the company had a contingency plan to continue its services. The Local president, Zak Radzak, who led the strike outside of the Aramark building, said nearly half of the 40 unionized workers here resigned in recent weeks over management and wages. âThey took jobs in the Hibbing area that pay less,â he said during interviews with the Mesabi Tribune.
