The ALP wants to rein in fixed-term contracts.

Australian employers would no longer be able to offer workers unlimited fixed-term contracts, if Labor takes government this weekend.

The party has proposed a cap on the number of consecutive fixed-term contracts employers can offer to four within 24-months.

After 2 years, employers would have to offer workers a permanent position.

It is intended to tackle job insecurity, with Labor arguing teachers, nurses and those in the public service in particular are caught in a cycle of precarious work.

There is currently no limit on the number of fixed-term contracts an employer can offer.

“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 party has also pledged to offer casual workers a clear path to permanent positions, giving them the option to request permanent jobs after 12 months working with the same company.
