An indefinite strike by 1600 Alcoa workers in Western Australia that began on August 8 has entered a new stage with the start of a Fair Work Commission (FWC) hearing in which the company is seeking to terminate the existing enterprise agreement. If the company's move is successful, workers at the multi-billion dollar company’s aluminium refineries and bauxite mines would be forced onto an inferior agreement that offers no job security and a possible wage cut of up to 50%.
