You must be kidding me about not treating 457 via holders poorly. Oh, 711, Dominoes and a host of high level "celebrity" restaurants etc have been taken to court for DELIBERATELY under paying their 457 workers. RE 711, after the court action some of the franchisors took cash off their reimbursed workers. The FW Ombudsman has said that 457 workers in Australia have, on their estimates, been underpaid to the tune of 1 billion.
