LANSING, Mich. — Michigan's 33,800 unionized state employees will have to reauthorize the deduction of dues from their paycheck every year or the contributions will stop under a rule change adopted by a Michigan panel over objections from Democratic Gov. Gretchen Whitmer and labor leaders. The Civil Service Commission, whose members were appointed by Republican former Gov. Rick Snyder, approved the revision 3-1 Monday. Starting in October, an authorization to deduct dues will expire if it wasn't authorized or reauthorized in the previous year. Of the state’s 48,000 employees, 33,804 — or 70% — are represented by a union.
