Senior government ministers have rejected union calls for changes to the Fair Work Act following the forced termination of industrial action at Qantas.
The ACTU has said a Fair Work Australia decision proved the system was weak and gave employers the upper hand.
The independent tribunal ruled that both Qantas and unions terminate industrial action and enter settlement talks after the airline grounded its entire fleet on Saturday and threatened a lockout of staff.
Unions believe other big employers will use similar tactics to bring industrial action to an end.
Tourism Minister Martin Ferguson said the Act had delivered over the weekend.
"The government's call was absolutely correct - be decisive, argue for a termination," he told reporters in Canberra.
"The dispute is over, the planes are in the air."
Acting Prime Minister Wayne Swan was of a similar view, saying the Act worked and "worked well".
Assistant Treasurer Bill Shorten questioned how a globally sophisticated company, such as Qantas, allowed itself to get to such a point in an industrial dispute.
"I think that the current Act served the Australian public well," he said.
Mr Shorten, a former trade union leader, said he did not think many employers would be rushing to use the Qantas strategy.
