Nissan workers in Canton, Mississippi, will vote today on union representation by United Auto Workers. In advance of the election, the National Labor Relations Board (NLRB) has issued a complaint alleging unfair labor practices. Nissan has threatened the 3,700 employees with loss of wages and benefits and threatened to close the plant if employees do support a union and promised increased benefits and improved conditions if they oppose.

“Nissan is running one of the nastiest anti-union campaigns in the modern history of the American labor movement,” says Gary Casteel, secretary-treasurer of the United Auto Workers (UAW) and director of the international union’s Transitional Department. He asked company investors and policymakers around the world to join in to call a halt to Nissan’s illegal and unethical behavior.

Ever since the election petition, Nissan has delivered daily threatening anti-union messages via video and mandatory meetings. The company has a history of unfair labor practice conduct in Mississippi and has had multiple Occupational Safety and Health Administration (OSHA) citations issued against it for violations of federal safety and health laws. OSHA fund the company “did not furnish employment and a place of employment which was free from recognized hazards that were causing or likely to cause death or serious harm to employees.”
