Smelter workers will forgo any wage rise in the next two years under a new enterprise bargaining agreement struck with Nyrstar.
In the third year of the agreement, the workers will receive a four-percent pay increase.
Australian Workers Union organiser Mick Hopgood said some of the agreement was “commercially sensitive” and had been deleted from public records.
This relates to a bonus to be applied when certain qualifications are met.
Negotiations between the union and the company had been protracted.
At one stage, the possibility existed that the workers could be switched to a different industrial award. As the stakes increased, workers considered strike action.
The company said talks had focused on the financial position of the business and any associated impact of wage increases.
