POSCO Union Strikes for First Time Since 1968 Founding

POSCO's union initiated its first strike since 1968 after wage negotiations failed. The strike affects key production lines and could disrupt supply to major industries. The union demands a 7.1% pay raise and other benefits, while management cites financial constraints. POSCO's operating profit fell 43.3% in the first half of the year. The dispute also involves the direct hiring of subcontracted workers, a contentious issue for the union.
