Workers at BHP Group’s Escondida copper mine in Chile are set to begin a strike after wage negotiations do not reach an agreement before a midnight deadline, according to Bloomberg. Union leaders say the latest talks fail to produce a settlement, moving the dispute toward industrial action.

Other coverage describes the deadline as arriving as BHP’s final offer expires. The Rio Times reports that BHP’s last proposal is 28 million Chilean pesos per worker (about US$28,700), with supervisors considering a possible walkout as mediation time runs out. Bloomberg also frames the situation as a last attempt to avert a strike, noting BHP improves its offer during mediated talks, while industrial action at another Chilean copper mine involving Antofagasta Plc features workers returning to negotiations.
