Mechanics at Colombia’s main coal mining companies, including Cerrejon and Drummond, went on strike on Wednesday over pay and conditions, a stoppage that will affect output if it continues long enough, a union leader told Reuters. The roughly 3,500 employees from maintenance contractor Dimantec have downed tools after rejecting a pay offer from the company, leaving mining companies at risk of having to scale down or halt operations if machinery cannot be kept running.
