Piece rate — The regular rate of pay for an employee paid on a piecework basis is obtained by dividing the total weekly earnings by the total number of hours worked in that week. The employee is entitled to an additional one-half times this regular rate for each hour over 40, plus the full piecework earnings. Example: An employee paid on a piecework basis works 45 hours in a week and earns $315. The regular rate of pay for that week is $315 divided by 45, or $7.00 an hour. In addition to the straight-time pay, the employee is also entitled to $3.50 (half the regular rate) for each hour over 40 — an additional $17.50 for the 5 overtime hours — for a total of $332.50. Another way to compensate pieceworkers for overtime, if agreed to before the work is performed, is to pay one and one-half times the piece rate for each piece produced during the overtime hours. The piece rate must be the one actually paid during non-overtime hours and must be enough to yield at least the minimum wage per hour.
