I was working as a security entertainment manager in Las Vegas until January. I got stuck out of town due to COVID-19. During this time my two supervisors were fighting with eachother. When I got back I sat down with my big boss who told me that they were removing all security managment positions. This came with a pay decrease and a loss of title. Before I left on my family emergency, I brought up dangerous health conditions for my security team (For example too loud music, and dangerous chemical usage). I came back to the demotion and pay decrease so I quit. Should I have done anything to complain against the company?
