The Chicago Symphony Orchestra Association says orchestra musicians have gone on strike after rejecting proposals for a three-year contract.
The organization says the contract would have provided musicians with a minimum base weekly salary of $2,795 in the first year, $2,835 in the second and $2,910 in the third.
The previous weekly base minimum salary is $2,785.
Orchestra Association President Deborah Rutter says the organization is "committed to reaching a fair agreement" and regrets any inconvenience the strike causes patrons.
She says musicians rejected the organization's final offer Saturday.
Officials with the Chicago Federation of Musicians, which represents the musicians, did not immediately return a phone call for comment Saturday night.
A Saturday night performance was canceled.
