The 135-member "Albemarle Salar" union, which consists of roughly half the workers at the company's key Salar production plant, went on strike in August over working conditions.
The company says the strike caused a reduction in the pumping of lithium-rich brine at the Salar plant, where the strike occurred, but overall production from its La Negra chemical plant, where brines are processed into battery grade lithium carbonate, was not affected.
