The U.S. Dept. of Labor requires time and a half pay for all hours over 40 worked in a work week. (I think only if employee status.) We are considered piecemeal workers and indeed are eligible for OT pay.
This is to be paid at time and a half of your calculated average pay.
I think Nuance is good about paying OT pay as you log in and out on their time clock.
It is time we start including OT hours on our invoices.
You might want to calculate your average hourly rate over a period of time and go by that.
Here is the law http://www.dol.gov/dol/topic/wages/overtimepay.htm
