Its a state issue. The following is coutresy of Grist who posted this source in the Earyl Release thread.
"In reality, time limits regarding payment of wages to terminating employees are established by state law and are normally quite stringent. Employers should thus ensure that they are familiar with the wage payment laws in each state in which they have employees. In California, for example, discharged employees must be paid wages earned at the time of discharge. Moreover, employees who resign must be paid within seventy-two hours of the effective date of the resignation unless seventy-two hours' notice was given, in which case payment must be made at the time the resignation is effective. In Connecticut, employees resigning must be paid not later than the next regularly scheduled payday. If the employee is discharged, however, payment must be made not later than the next business day following the discharge. In New York, employers are required to pay all terminating employees, regardless of whether they resign or are discharged, not later than the regular payday for the pay period during which the termination occurred.
