Some members of the Louisville Orchestra’s musicians union are staging a protest at the orchestra’s headquarters this afternoon as their contract impasse continues. The musicians had already said they would reject management’s latest contract offer. They had until today to consider a proposal that outlines specific expectations for rehearsal and performance attendance. The orchestra has filed for Chapter 11 bankuptcy and wants to cut the number of annual performances and musicians to save money. The musicians’ union opposes the changes and says the orchestra can find ways to raise enough money to continue at its current strength.A statement from the orchestra says the two sides have agreed to continue meeting with a federal mediator, although some musicians told WFPL today that they don’t want to continue those talks without the presence of an industry expert.
