In the three-year contract negotiations, Drummond offered a 4.7% wage increase in the first year, followed by a 1.25% hike plus inflation in the second year and a 1.5% raise plus inflation in the third year.

Workers are also concerned about layoffs once Drummond’s direct ship-loading facility starts operations at its Ciénaga port in the Magdalena department. Drummond is spending $350 million on the project, which is scheduled to start operating by year-end. The company guaranteed that a minimum of 70% of employees will be given a similar job either at the port or at the mine once the new facility starts up.
