Thank you for your response dated June 6th, 2011. In acknowledgement, we would like to respond to a number of issues related to your operations in Durango, Mexico, and provide some further evidence to buttress our outstanding concerns with Excellon‟s labor rights record...Interviews with the approximately 60% of the workers at La Platosa mine conducted throughout 2010 detail that the workers were not even aware that they were unionized...This information brings into question Excellon‟s claims of a satisfactory relationship of the workers with said union...As a matter of international human rights law, you must know, the existence of a union in the company workplace does not prove per se that the rights of workers to freely associate with a union of their choosing have been upheld...Second, Excellon claims that it was not informed by community members of the existence of harassment of workers by local management for their labor rights promotion...[but] we have received and confirmed confidential testimony from workers on site that Ing. Gurrola pressured them to sign a letter stating disinterest in unionizing. [The Business & Human Rights Resource Centre invited Excellon to respond to this letter. Excellon did not respond]
