How do you protect elders when a company promotes a caregiver who does drugs?

Carson Plaza Retirement has a manager there that has requested "meth". She was assistant manager at the time and it has escalted to where she grabbed my arm and jerked me almost to the floor in the community dining room. She was reported and the corporate office did nothing, again. I have been a caregiver in the building for 22 years and have never had a rpoblem with any other managers. I do not know where to turn for help. I have contacted the AG office, Comissioner of the Board of Labor and they do not know where to send me. I need help.
