Kellogg has agreed on a new contract with the union representing the Froot Loops maker’s striking employees at its U.S. breakfast cereal plants, a local union president said on Thursday.

It could open the door to 1,400 employees returning to work after Christmas. This follows workers rejecting a prior agreement reached earlier in the month.

Kellogg had to vote down the agreement in order for it to permanently replace striking workers. This was a move that U.S. President Joe Biden termed an “existential assault on the union’s jobs and livelihoods”

According to the union, progress was made regarding the main issues of the previous agreement. These include cost-of-living wage adjustments for all employees as well as the elimination of “legacy employee”.

Kellogg explained that “transitional employees have an expedited, defined path towards legacy wages and benefits in comparison to the current contract.”

President of Omaha’s local union, Dan Osborn said that voting for the new agreement would take place on Sunday, and the votes would then be counted Tuesday.

He said, “If the ratification was done we will return to work Dec. 27.”

However, there was no progress made on several fronts, such as the limitation on employees of lower tiers.

The striking workers suggested that Kellogg’s two-tiered employee system, where transitional workers get less pay and benefits than those who are longer-tenured, could reduce the power of the union by eliminating the limit on the lower-tier employees.

Since Oct. 5, the workers went on strike after expiring their contracts. The union and packaged food maker disagreed about pay and benefits, and negotiations for the workers over compensation and other issues stalled.
