Argentina: A dispute between a supplier and its union has caused Loma Negra to switch off two kilns at its Olavarría cement plant. The Clarín newspaper has reported that the argument is between Minerar, which provides the plant’s raw limestone, and the Asociación Minera Obrera Argentina (AOMA), which represents miners’ interests. The union says that miners are underpaid. They receive US$245/yr less than cement plant workers.
The producer said, “It is the leading Argentine cement company, with approximately 45% of total sales in the country. This shortage will impact the country's economy, which had been recovering after the pandemic." The union rejected a mandatory conciliation on 3 December 2020. Negotiations began in October 2020.
