Labor to rein in fixed-term contracts

Australian employers would no longer be able to offer their workers an unlimited run of fixed-term contracts if Labor wins the federal election.

The opposition wants to cap the number of consecutive fixed-term contracts employers can offer to four within 24-months, after which they would need to offer workers a permanent position.

The move is aimed at tackling job insecurity, with Labor arguing too many Australians - particularly teachers, nurses and those in the public service - are caught in a cycle of precarious work.

Under current laws, there is no limit on the number of fixed-term contracts that can be offered.

"Labor's reforms are about protecting workers and giving them and their families a fair go," Labor employment spokesman Brendan O'Connor said on Thursday.

"Giving workers and their families some certainty to be able to plan ahead - to pay the rent or even plan to buy a house or a car."

The opposition says it would consult with stakeholders to rollout the change to prevent any "unintended consequences".

The announcement comes after Labor leader Bill Shorten last month promised casual workers a clear path to permanent positions.

Under proposed changes, casuals would be allowed to request permanent jobs after 12 months working with the same company.
