That Starbucks cup that held your morning skim latte or the Chinet paper plates you've got packed up for a picnic this weekend were likely made by workers at one of Huhtamaki's 21 plants in the United States...Today at Huhtamaki's Commerce, Calif., plant, workers asked management to "engage in a good faith dialogue" about working conditions in the plant where temperatures can reach 100 degrees or more and where workers are subject to a disciplinary system they say management uses "only as a tool to punish workers." The letter they presented to Huhtamaki's plant managers also urged those managers to refrain from retaliating against the workers for their actions... Said one worker: "We knew that when we tried to talk to management about these issues individually, nothing changed. When we all got together we realized that if we all asked for changes together, there was no way they could ignore us. All we want is for them to treat us the same way they treat their union employees."
