Workers at one of the nation’s largest meatpacking plants who staged a multiweek strike have reached an agreement with plant owner JBS USA, the company and labor union representatives announced Sunday.

The Swift Beef Co. plant in Greeley, Colorado, will immediately return to normal operations after weeks of uncertainty, JBS USA said in a statement.

The agreement comes after thousands of workers at the meat processing plant led a three-week strike with the United Food and Commercial Workers Local 7 Union in a bid for higher wages and better health care. The strike ended April 4 after JBS USA agreed to resume negotiations.
