Hi y’all, western US here and I got a question. My wife works for a call center as a mid level manager but is still in work flow. Every 4th weekend she has to be “on call” from 6am to 4pm with no extra pay and no extra days off during the week. Basically every 4 weeks she works 12 days straight and is salaried at 40 hours. When it has been brought up to her management or HR team she is told “you are only needed to be available in an emergency” however there are multiple “emergencies” every weekend such as if someone calls out she has to “cover” their shift. Is this legal? Advice would be greatly appreciated.
