Wage negotiations between organised labour and Gold Fields at its South Deep Gold Mine near Westonaria have entered a critical phase, with unions accusing management of "arrogance and disrespect" as both sides remain sharply divided over salary increases.
The fifth round of wage talks between trade unions UASA, the National Union of Mineworkers (NUM), and Gold Fields management was held on Friday, where tensions reportedly escalated during plenary discussions.
UASA spokesperson Abigail Moyo said the unions were deeply concerned about the state of negotiations, warning that the company’s conduct was undermining constructive engagement.
“The unions have criticised the company’s conduct during the negotiations, citing the need for mutual respect and professional conduct to ensure a mutual understanding, which is especially important for the members and all workers employed by the company,” Moyo said.
NUM and UASA accused Gold Fields executives of displaying “pomposity and arrogance” during negotiations, warning management to immediately end what they described as instructive and disrespectful behaviour.
At the centre of the dispute is a widening gap between labour’s wage demands and the company’s latest offer.
The unions are demanding an 11% salary increase for workers in Categories 4 to 8, who represent the lower-paid employees, and a 9.5% increase for artisans, miners and officials. However, Gold Fields has offered 7% for Categories 4 to 8 and 5.7% for artisans, miners and officials.
Organised labour argues that the company’s proposal does not fairly reflect workers’ contribution to Gold Fields’ strong financial performance, particularly amid elevated international gold prices that have boosted profitability across the sector.

The mine employs almost 4,600 people directly, either as full-time employees or contractors.
The unions also argue that mineworkers are facing mounting financial pressure from rising living costs and inflation, making meaningful wage adjustments essential.
In an effort to strengthen its position ahead of the next round of talks, the NUM has formally invoked Section 16 of the Labour Relations Act, which compels employers to disclose relevant information to representative trade unions during collective bargaining processes.
The unions have requested detailed information from Gold Fields, including revenue figures, profitability data, remuneration records and internal dividend, and bonus payout structures.
Union leadership said the information was necessary to allow workers to properly assess the company’s financial position and bargaining stance.
The outcome of the negotiations may now rest with workers themselves, with unions set to report back to members during a mass meeting scheduled for Tuesday. Workers will ultimately decide whether to accept or reject the company’s latest wage offer.
The labour tensions come at a time when Gold Fields has reported a strong start to 2026, supported by higher global gold prices and increased production.
Earlier this month, Gold Fields CEO Mike Fraser said the group delivered solid operational and financial results during the first quarter of the year, generating strong cash flow as sales volumes and gold prices increased.
Group attributable gold-equivalent production rose 15% year-on-year to 633,000 ounces, while net debt declined by 34% to $1.31 billion following the payment of a final dividend of $1.23bn in March.
Fraser said operations had performed largely according to plan, driven in part by strong production at the Salares Norte mine in Chile following the achievement of steady-state operations late last year.
However, the company also warned that rising global input costs could place pressure on its cost guidance for the remainder of the year.
Fraser said the outbreak of conflict involving Iran had triggered sharp increases in key commodities and operating expenses across the mining sector.
Since February, Gold Fields has experienced diesel price increases of between 30% and 70%, freight cost increases of about 40%, LNG price increases of roughly 30%, and higher costs for explosives and cyanide.
“The forecast impact of this, assuming an oil price of $100 per barrel, is between $40/oz to $50/oz on a portfolio level,” Fraser said.
While management said it remained confident of staying within its production guidance, it acknowledged that continued inflationary pressures could significantly affect operating costs.
