A new wage deal struck by Domino's Pizza and the shoppies union will see part-time employees trade regular working hours for a 2¢ an hour pay rise, in a move a rival union says will "casualise" permanent work conditions.

The pizza shop and the Shop, Distributive and Allied Employees' Association (SDA) announced the deal on December 28, after the workplace tribunal in November tore up previous agreements that saw workers miss out on penalty rates worth tens of millions of dollars a year.

Domino's said the new enterprise bargaining agreement would deliver among the highest wages in the fast food industry for its more than 20,000 workers, but would not disclose pay rates and other details.

A copy of the proposed agreement has now been obtained by Fairfax Media, and shows that entry level workers will be paid a base rate of $20.10 per hour - 2¢ more than the basic wages safety net.
