CHIPPEWA FALLS, Wis. – The Teamsters Union began a strike against the Leinenkugel’s brewery. Union members said the brewery’s new owner, Molson Coors, has offered only niggardly wage improvements at a time that Leinenkugel sales swelled from $10.3 billion $10.7 billion. The walkout and picket line followed a 98% vote to authorize the strike. A Molson Coors executive, Adam Collins, said the company had offered “a competitive offer that exceeds local-market rates.” Adams said the strike won’t affect Leinenkugel availability.
