A senior woman that was forced to work more than 40 hours in a week with no overpay in the ITT project is suing the management at Houston. She reported that she is forced to work minimum 50 to 60 hours in a week and during the recent go-live she was forced to work more than 80 hours in a week, with no overpay.

Pay for Overtime
The FLSA does not limit the number of hours an employee may work in a week, unless the employee is a minor. But it does require that any covered worker who works more than 40 hours in one week must be paid at least one and one-half times his or her regular rate of pay for every hour worked in excess of 40.
In addition to the FLSA overtime provisions, a number of state laws also define how and when overtime must be paid. Some states measure overtime on a daily, rather than weekly, basis. In these states, workers who put in more than eight hours a day are generally entitled to overtime, even if they work a total of 40 or fewer hours in a week. (To learn your state's overtime rules, select it from the list at Wage and Hour Laws By State.)
