I live in and work in CA. I was told that I am a salary exempt employee. I am the Administrative Service Manager- basically the office manager. We are open from 8 a.m. to 5 p.m. Monday through Friday. Closed on Saturday and Sunday. Can I be asked to work evening hours and weekends if so how much advance notice should be given to me? Also if the work is not part of my workload is asking me to come in and work something I must do?
