The USO in a statement says it categorically rejects the model of new contracts that Ecopetrol’s administration is proposing. The union calls it an attack against the workers, as it will allow contractor firms to lower headcount, decrease salaries and hierarchical ranks of works, increase the work load through “multifunctional” workers. This will expose workers to a higher risk of accidents, breaking the internal policy of Ecopetrol called “Work Safely, Clean Barrels”.
