CHICAGO (AP) — Musicians with the Chicago Symphony Orchestra will receive a 4.5 percent salary increase over three years under a new contract but will also have to pay increased health care costs.

The symphony released contract details Wednesday, the same day the symphony association’s trustees ratified the contract. Musicians went on strike Saturday, forcing the cancellation of a performance. The Chicago Federation of Musicians and the symphony reached a tentative contract on Monday evening. Musicians ratified the contract on Tuesday morning. Negotiations began in July.

The musicians’ pension plan will remain unchanged under the contract. Their weekly base salary will be $2,910 in the final year of the contract.

Symphony officials say all previously scheduled orchestra engagements will go on as planned.
