California hospitals are criticizing a nurses' strike that began on Tuesday over a lack of adequate equipment and training standards for treating patients with Ebola, saying that the protest was political and that nurses' concerns are unfounded. On Tuesday, 18,000 Kaiser Permanente nurses launched a two-day strike in part to protest a lack of adequate equipment and training standards for treating patients with Ebola. The strike affected 21 hospitals and dozens of clinics in California, according to National Nurses United spokesperson Charles Idelson. Nurses at Sutter Tracy Community Hospital and Watsonville Community Hospital also went on strike, according to the union.
