The Construction Forestry Mining and Energy Union said the workers had also won other entitlements such as a better Accident Pay clause to be paid at a rate as at work.
CFMEU NSW southwest vice president regional Bob Timbs said the agreement contained significant gains that clawed back the substantial losses inflicted on labour hire workers over the recent years.
“The solidarity and determination of the Delta workers has paid off with our union negotiating a 14.5% increase in their hourly rate, a 23% increase in bonus and a casual conversion clause that allows all employees to move to permanent employment after 12-months,” he said.
Timbs said the agreement with Delta was setting a precedent for other labour hire employees and improved wages, conditions and job security provisions would flow through.
“They have set a new benchmark that many others will benefit from,” he said.
“They have shown what you can achieve by taking a stand and backing it up with action with the Union beside you all the way. They deserve great credit.”
A South32 spokesperson told Australia’s Mining Monthly: “South32 is pleased with the resolution and outcome of the matter between contracting firms and their employees.
“We value the role of our contractor workforce and the contribution they make to ensure the sustainable, safe and reliable operation of our Appin mine,” the spokesperson said.
