With nearly 2 million cases of reported workplace violence each year and many more unreported, a comprehensive workplace violence program is necessary, according to OSHA. The sexual assault of a home health care worker and subsequent investigation has affirmed the importance of such a program. OSHA opened an investigation following a complaint on Feb. 1, 2016, from an employee of AndVenture Inc. doing business as Epic Health Services after a home care client assaulted an employee, despite being warned by another worker about sexual assaults.
