What are the OT laws like over there? 84 hours would mean quite a lot of OT income here in California - for the first 40 hours, time and half after 8 hours in a single day, double time after 12 hours in a single day. After 40 hours, everything's time and a half and if you work a 7th straight day, time and half for the first 8 hours worked, and double time after that.
Probably salaried.
