Embattled pizza giant Domino's faces calls for an independent compensation scheme for exploited workers as well as heightened scrutiny from the workplace regulator and the Senate amid allegations of widespread wage fraud.

The chairman of the migration workers taskforce Professor Allan Fels said Domino's needed to take the lead and arrange a "genuine" and "independent" compensation scheme for underpaid workers, who he believes could be in the thousands.

"It is hard to believe that underpayment at Domino's doesn't number in the thousands," he said. "Once systemic underpayment occurs, it spreads quickly through much of the system."

Fairfax Media on the weekend exposed allegations that Domino's franchisees were engaged in widespread underpayment of workers and, in some cases, visa fraud. It also produced evidence that many franchisees struggled to make a profit.
