Democrats and labor unions opposed the legislation and placed a referendum on the November 2011 ballot to repeal SB 5. SB 5 also "sparked numerous protests with thousands of union workers and other opponents descending on the Statehouse, mirroring similar demonstrations in Wisconsin and injecting Ohio into the national debate over Republican governors' attempts to curb public workers' collective bargaining rights." Kasich and other supporters of SB 5 characterized the legislation as a necessary measure "to help public employers control labor costs" and reduce tax burdens to make Ohio more competitive with other states, while labor unions and other opponents characterized the bill as "a union-busting attack on the middle class."
