Workers at PT Argo Pantes Tbk (JSX:ARGO), Indonesia's largest integrated cotton and cotton-blended textile company, have staged a protest to demand better wages. Argo said in a letter to the Surabaya Stock Exchange that the protest took place in the company's factory in Tangerang on February 12, 2001, and that it had affected the company's production. But the loss caused by the incident had not been calculated and Argo promised to report it further, the letter said.
