Key Points
1
Strike set to begin at 7 a.m. MT on Sept. 3, affecting about 420 workers at Stillwater East and the Columbus metallurgical complex; Stillwater East and Columbus are covered by a single agreement, while East Boulder is on a separate agreement.

Sibanye says the company spends about $30 million annually on employee health care, a factor cited in negotiations over proposed changes to benefits and costs.

Incentive-pay changes are central to the dispute: union officials say the shift to a team-based incentive system could cost some workers thousands of dollars and, in some cases, result in about a 13% reduction in wages, while the company contends the total incentive pool would grow and be distributed more evenly among hourly staff.

CEO Richard Stewart has warned that without timely implementation of the productivity- and transformation-driven plan (including mechanisation and upgraded work practices), there may be no viable basis for the continued operation of the U.S. PGM sites.
About 420 workers at Sibanye-Stillwater's U.S. platinum operations launched a strike at 7 a.m. MT on September 3, ending more than four months of failed contract talks. Billings Gazette reports the union disputes proposed changes to health care and incentive pay, with some workers facing potential wage cuts of up to 13%.
CEO Richard Stewart warned that without sweeping changes to boost productivity, the company may shut down its U.S. operations entirely. Montana Standard notes the company has posted nearly $500 million in losses, putting the long-term viability of the Stillwater East mine and Columbus metallurgical complex at stake.
The Core Dispute: Health Care and Pay Structure
The strike centers on two issues: rising health care costs and a shift to team-based incentive pay. Sibanye spends roughly $30 million annually on employee health benefits, a burden the company wants to restructure. North American Mining reports union leaders argue the new incentive system could slash earnings for some workers by as much as 13%.
The company counters that the total incentive pool would actually grow, but be distributed based on productivity gains rather than individual output. Sibanye has offered a 5% wage increase for 2026 as part of its package, but the union says the overall deal fails to protect workers from financial harm.
CEO Signals Possible Shutdown Without Major Changes
Richard Stewart delivered a stark warning: the company cannot survive without overhauling operations. Montana Standard reports he said ongoing losses mean there is no viable future for U.S. PGM sites without the planned productivity improvements, which include mechanization and upgraded work practices.
The U.S. operations are running near break-even, squeezed by low palladium prices and rising costs. Stewart framed the transformation plan as essential to preserving jobs in the region. The company says it remains committed to negotiating a deal that ensures long-term sustainability.
Two Separate Agreements Complicate the Dispute
The strike affects workers at Stillwater East mine and the Columbus metallurgical complex, which operate under a single contract. Mining Connection notes the East Boulder site remains under a separate agreement and is not part of the current labor action.
This split creates a more complex situation for the company. It must manage operations across multiple facilities while negotiations continue. Union officials argue the company failed to bargain in good faith, pushing workers to strike to protect their livelihoods and demand fair contract terms.
