OAK CREEK, WI – Operating Engineers Local 420 announced today that Business Manager Mark Maierle will retire effective October 31, 2018 after a 40-year career as an operating engineer. Maierle heads the statewide local representing skilled workers in utility, refining, building maintenance and other equipment operation industries in Wisconsin.
“It has been an honor to serve the union membership as Business Manager since 2000,” said Maierle. “Our members perform excellent work striving to make our signatory employers successful. I am very thankful to the members, the executive board and staff for their support and their commitment to the labor movement.” Maierle added, “I have truly enjoyed working each day with talented and dedicated colleagues. Promoting workers, providing training opportunities and seeing people embark on family supporting careers with great employers has been a privilege.”
The Local 420 Executive Board thanked Maierle for his dedicated service to the union and the labor movement in Wisconsin. “Mark has done a great job of leading our union since we created our statewide local in 2012,” said Local 420 President Patrick Kelly. “He is a highly respected and progressive leader who guided the local union on a strategic path to sustainable success.”
Assistant Business Manager Alex Tetzlaff was appointed by the Local 420 Executive Board to complete the remainder of the business manager’s term expiring in 2020. Tetzlaff has been an Operating Engineer since being hired by Wisconsin Public Service Corp. in 2003 and has served the members as a full-time staff representative since 2013. He has held various Local 420 officer positions including Vice President. Tetzlaff is a trustee on the Power 420 Training and Education Trust and is the Chairperson of the Midwest Utility Workers Coalition.
According to Maierle, “Succession planning has long been a priority of our local union and we are proud to say we have a deep bench. Our business agents, chairpersons and stewards are talented and well trained as representatives and union leaders. The union will be in great hands with Alex leading this dedicated team.”
Kelly echoed these thoughts stating, “Alex Tetzlaff is well prepared for the job of Business Manager. While Mark’s experience and vision will be missed, our leadership team is strong and we are confident that Brother Tetzlaff will be successful in his new role.”
