Work M-F 40 hours M-F 8:30 am - 5:00 pm, paid hourly.
Work for a company similar to a Triple A roadside business.
Expected to answer cell phone calls from customers and carry laptop at all times during evenings and weekends, my normal time off.
Only paid for time worked away from the office if I answer a call from a customer and I completely dispatch the roadside call to tow truck company. Then I'm only paid $15 for each dispatched call that doesn't cancel before the tow truck arrives at the problem location.

Should I be paid for all this time during my time off that I'm expected to answer calls from customers?
