Workers at a South Auckland Foodstuffs distribution centre have walked off the job and embarked on a seven-day strike.
The strikers are calling on Foodstuffs, which owns Pak'nSave and New World supermarkets, to do more to ensure temporary workers receive decent employment conditions.
They had made bargaining claims and given letters from temps describing the toll their work and the lack of employment protection had on their lives.
"Foodstuffs have a long history of using exploitative labour-hire contracts to avoid their employment responsibilities. The workers have had enough" said the workers' representative, FIRST Union organiser Lisa Meto Fox.
"Most temps are still working with no guarantee of hours and very few protections under employment law. We've come across cases where temps were harassed simply for calling in sick. Something has to change."
