The BlueOval SK plant, owned by a partnership of South Korea's SK On and Ford, is the latest battery battleground for the union.

The UAW union has petitioned the National Labor Relations Board (NLRB) to hold an election at the BlueOval SK battery plant in Kentucky.

The Kentucky autoworkers, who want to join the United Auto Workers, filed for a union election Tuesday, a key development in the union’s campaign to organize Southern auto-factories and EV battery facilities.

Workers at a Kentucky BlueOval SK Battery Park filed for an election to join the United Auto Workers union Tuesday, marking the new year’s first major union election petition filed in the South —and one that could foretell future union activity in Tennessee.

Workers at a Ford Motor Co. joint-venture battery plant in Kentucky have formally asked the federal government to hold a vote on joining the United Auto Workers, the union said.

The UAW is trying to rush BlueOval SK into unionization before our full workforce has the opportunity to make a truly free and informed choice,” a company spokesperson said.

A supermajority of workers at BlueOval SK filed a petition with the National Labor Relations Board for a vote to form their union with the UAW.

The United Auto Workers (UAW) is seeking an election at Ford's BlueOval SK battery plant in Kentucky. Despite hiring delays, the UAW claims a strong majority support within the current workforce for unionization.

The United Automobile Workers union asked a federal labor regulator to conduct an election at a factory Ford jointly owns with a South Korean battery company.
