The work stoppage at the St. Louis Symphony has been remarkably civil thus far, but tempers are beginning to flare over the issue of health insurance, which was cut off to the musicians when they rejected management’s final contract offer. The SLSO had prepaid the musicians’ premium, and received a rebate from the cancellation. Meanwhile, the 2-year-old son of an orchestra cellist had a seizure last week, and his mother found herself stuck with a major hospital bill when her insurance was found to have been terminated. The musicians claim that their health insurance was never affected during previous work stoppages.
