The Chicago Symphony Orchestra has agreed to a tentative three-year contract with its musicians union.

According to the Associated Press, the orchestra said that the agreement was made before the contract expired on Sunday, Sept. 17, 2023.

In a statement both sides said the deal “improves working conditions and wages for the musicians,” but terms of the tentative agreement will not be released until the contract is ratified.

The deal will now have to be voted by the CSO board of trustees and the orchestra members in the Chicago Federation of Musicians.

If approved the new contract will be in place through September 2026.
