Locked-out workers at American Crystal Sugar factories in Minnesota, Iowa and North Dakota will soon be voting on the company’s contract offer a third time. The vote is Saturday, June 23rd. Union members overwhelmingly rejected the contract offers last July and November, saying it takes away job security and that wage increases would be offset by health insurance costs. The decision to hold another vote came after representatives of the two sides met last week for a fourth time with a federal mediator but couldn’t end the impasse. The dispute has lingered for more than 10 months. American Crystal last August 1st locked out about 1,300 union workers at sugar beet processing plants in the three states and filled their positions with replacement workers.
