ROANOKE, Va. - Saltville, Va.-based Southwest Virginia Community Health System, Inc. (SVCHS) will pay $30,000 to settle a sexual harassment lawsuit filed by the U.S. Equal Employment Opportunity Commission (EEOC), the agency announced today.
The EEOC's suit alleged that Karen Ross, a female receptionist at SCVHS's Troutdale, Va., clinic, was sexually harassed by a male patient during her employment at the clinic. According to the EEOC's complaint, Ross complained to her supervisor about the patient's sexually harassing conduct, but no action was taken to stop the abuse. An employer is liable for acts of a non-employee if the employer knew about the conduct and failed to take immediate and appropriate corrective action.
