BHP has sued the workers' union at its Spence copper mine in Chile, seeking about $8.6 million over two work stoppages in June and July that it says were illegal. It adds to labour tension across Chile's copper mines.
At a glance
- BHP says the stoppages happened outside the legal negotiating period and significantly affected the mine.
- The union was pushing for a special bonus of 5 million pesos ($5,102) per member.
- Spence is BHP's second-largest operation in Chile, after Escondida.
Background
Chile is the world's biggest copper producer, and its mine unions often strike to win better pay and benefits, usually during formal contract negotiations. Any lost output in Chile matters to global copper supply, so labour disputes there are closely watched.
What happened
BHP has filed a lawsuit against the union at its Spence copper mine in northern Chile, according to a court filing seen by Reuters on Thursday. The company says two work stoppages in June and July were illegal because they took place outside a scheduled negotiating period.
BHP alleges the stoppages "significantly" affected operations and is seeking roughly $8.6 million in compensation. The company confirmed in a statement that it had filed the lawsuit. The union declined to comment.
What the dispute is about
The union wanted a special bonus of 5 million pesos ($5,102) for each member, the filing shows. That bonus was not part of its existing agreements with BHP. The stoppages were meant to pressure the company into paying it.
Copper mine unions in Chile usually strike during contract negotiations. BHP's lawsuit targets action taken outside the scheduled negotiating period, which it says made the stoppages illegal.
What it means for copper
The lawsuit adds to a tense week for Chilean labour relations. BHP only recently reached a preliminary deal with supervisors at Escondida, the world's biggest copper mine, avoiding a strike. At Antofagasta's Centinela mine, two unions declared a strike after the third quarter ended.
Labour disruptions in Chile are one reason copper supply looks tight, with London Metal Exchange prices near record highs this month.
Our read
Outlook: neutral. The lawsuit concerns past stoppages, not current output. It does add to signs of labour friction at Chilean mines.
What to watch
- The union's response to the lawsuit and any court ruling.
- Whether labour tension spreads to further stoppages at Spence or other Chilean mines.

Other ways this could play out
