As the cold season is drawing nearer, the company expects fewer clients, and so it is considering curbing the activity of certain production lines, as well as reducing personnel at its Calarasi plant by December 1, it said in a press release.
During the period of lower activity the company will carry on with the verification, maintenance and repairs of its equipment, as well as current administrative issues, it added.
