The union said the Luxembourg-based company refuses to share 10% of profits for the 2021 financial year among more than 3,500 direct employees at the plant in the western state of Michoacan.
The steel company said the payments were made on time and that the sums claimed by the workers are “above the legal maximum.”
The company offered to pay a one-time bonus of six months’ salary, but the workers rejected it.
“ArcelorMittal Mexico regrets this decision because, in addition to the escalation of the conflict, it will have a serious impact and consequences … on the national production chain and the economy of the country given the importance of steel” , the company said in a statement.
ArcelorMittal manufactures wire rod and rods for construction, parts for the automotive industry and products for the energy sector.
