A Wollongong trade union leader said yesterday he fully supported a proposed international union campaign against BHP Billiton over its workplace practices, which unions claim are in breach of core labour standards. The International Metalworkers Federation (IMF) congress meeting in Sydney yesterday resolved to embark on the union campaign against BHP Billiton...Yesterday, the congress was briefed on reports that police and dogs were used against workers when BHP Billiton recently sacked 40 trade union activists in Mozambique for starting strike action over better pay. The congress also heard claims that BHP Billiton was disregarding the health of workers employed in Peru who were working 12-hour days in a mine in a mountain more than 4000m above sea level.
