Boeing and the workers’ union have agreed on a new contract proposal, the union announced on Saturday. This deal could end more than a month-long strike that has hampered manufacturers’ production.

The ratification vote is scheduled for Wednesday.

Acting US Labor Secretary Julie Su met with both parties earlier this week. “With the help of Acting U.S. Secretary of Labor Julie Su, we have obtained a negotiated proposal and resolution to end the strike that is worthy of presentation to members and worthy of your consideration,” said the International Association of Machinists and Aerospace Workers District 751 said in a statement Saturday.

The strike began on September 13 after more than 30,000 machinists overwhelmingly rejected a tentative agreement that would provide for a 25% wage increase over four years. Boeing later made a watered-down offer, but the union criticized it, saying it was not negotiated.

“We look forward to our employees voting on the negotiated proposal,” Boeing said in a statement.
