MOLINE, Ill. — More than 10,000 Deere & Co. workers went on strike Thursday, the first major walkout at the agricultural machinery giant in more than three decades.

The union had said its members would walk off the job if no deal has been reached Wednesday. The vast majority of the union rejected a contract offer earlier this week that would have delivered 5% raises to some workers and 6% raises to others at the Illinois company known for its green tractors.

“The almost one million UAW retirees and active members stand in solidarity with the striking UAW members at John Deere,” UAW President Ray Curry said.

Brad Morris, vice president of labor relations for Deere, said the company is “committed to a favorable outcome for our employees, our communities and everyone involved.” He said Deere wants an agreement that would improve the economic position of all employees.

“We will keep working day and night to understand our employees' priorities and resolve this strike, while also keeping our operations running for the benefit of all those we serve,” Morris said.

Workers were emboldened to demand more this year after working long hours throughout the pandemic and because companies are facing worker shortages.

“Our members at John Deere strike for the ability to earn a decent living, retire with dignity and establish fair work rules,” said Chuck Browning, vice president and director of the UAW's Agricultural Implement Department.

A handful of workers began forming a picket line outside the company's plant in Milan, a town in western Illinois near the Iowa border, about 15 minutes after strike deadline.
