POSCO workers began a two-day partial strike in Pohang and Gwangyang on Wednesday after labor talks over wages and compensation broke down. It is the first strike by POSCO workers since the company was founded in 1968. The union said about 120 workers joined the walkout, while management said the limited participation should have little impact on production. The union also warned of a 120-hour partial strike starting Sept. 16 if the dispute is not resolved.
