HB 3585 modifies employment policies for mental hospitals and mental health facilities in Texas. The bill expands the definition of "facility" under the Health and Safety Code to include mental hospitals and mental health facilities. It extends the prohibition on hiring individuals with certain criminal convictions, increasing the disqualification period from five to ten years for offenses such as assault, burglary, theft, and fraud. Additionally, mental health facilities are required to develop and provide written policies on drug testing and criminal history checks for employees and applicants who will have direct contact with patients.
