Members of the Chicago Symphony Orchestra went on a weeklong strike as a result of failed negotiations to renew their contract. The musicians are seeking long term sustainability through salary, benefits, and pension structure. The musicians claimed that management has asked them to take a reduction in salary and benefits despite the increased revenue from sales. Now that the strike has ended, both parties have reached a consensus, which involves the orchestra downsizing by four players, and management agreeing to a pay increase.
