Mercury Marine says it accepts the results of the second contract vote by its union workers. They approved a package of concessions that will reportedly keep 850 jobs from moving from Fond du Lac to a plant in Oklahoma. The union hasn’t revealed the exact vote count. Workers rejected the package the first time they voted. That vote wasn’t close. Mercury Marine says the approval will result in additional jobs coming to Fond du Lac. It also results in frozen wages for the next seven years, more health care costs passed on to workers, changes in workplace rules, the return of laid off workers and 30 percent lower pay for new hires at the plant.
