RACINE, WI—Unionized workers of tractor manufacturer CNH Industrial are striking after contract negotiations between the company and the union, United Auto Workers, broke down.

“We’re just out here trying to get what’s best for us,” said Alfy, McGee, a 14-year employee that works at the Case North plant in Mount Pleasant, WI. “It’s just our duty. It’s what we have to do. We have to stick together. It’s our union.”
