Congressman Bennie Thompson called a news conference Sunday to say he supports workers’ right to form a union.
Employees said they approached the United Auto Workers about starting a union at the Nissan plant.
The UAW has tried in the past to unionize workers at Nissan’s plant in Smyrna, Tenn., and at other foreign-owned auto plants in the South.
State NAACP president Derrick Johnson said his organization also stands behind workers’ right to unionize, “because it’s the right thing to do.”
The National Labor Relations Board said Friday no petition has been filed seeking a union vote in Canton.
