A trucking company that ceased hauling from Kroger’s Louisville, Kentucky, distribution center after reports its unionized workers there planned to strike is fighting federal demands to return and call back the former workers—three years later.

Nashville, Tennessee-based Quickway Transportation packed up at the terminal in December 2020 and furloughed about 65 employees, saying an anticipated strike could cause it “catastrophic damages and liability.” But the National Labor Relations Board soon alleged the move was intended to chill unionization at the company’s other locations.
