Further in that article it translates as:

The complaint specifies that the fundamental cause that generated and enhanced the potential for contagion at the enterprise and community level, as well as the failure and timely omissions of protocol and pure logic measures by all known and widely disseminated around the world, has to do with the entrepreneurial decision of managers and ceos to maintain and not reduce during the emergency , the staffing of workers but to support it in a number close to 1,000 workers, out of a total of 1,100 who usually perform there.

And still further you find:  

In this line of argument, it points out that the fundamental basic rule, both in public and private institutions, companies and associations, is and remains to be considerably lowered (the rule establishes at least 50%) the number of workers and therefore the reduction of the pace of activities of this type with large numbers of people in the camp.

It should be noted that other companies in the field operating in the province, such as Sales de Jujuy, Mina Pirquitas, Mina El Aguilar, among others, reduced their workers' plant during the emergency, complying with the aforementioned preventive regulations, adding the very strict procedures for testing their personnel.

For this reason, the main criminal responsibility rests with the management body of the company and ceos of EXAR, who made the corporate decision to maintain the number of active workers of the usual plant and thus agglomerate as many workers against the recommendations, demands and practices adopted by the rest of the companies dedicated to mining.
