Unionized truckers in Korea launched a nationwide strike Thursday, the second of its kind in less than six months, stoking worries over supply disruptions amid post-pandemic recovery efforts.

The government vowed to take a zero-tolerance stance against the strike, warning of stronger action than the last time.

The latest walkout came about five months after the truckers staged an eight-day strike in June, which resulted in massive delays of cargo shipments, and other logistics and supply disruptions across the country.

More than 22,000 of 25,000 members of the Cargo Truckers Solidarity Union, under the wing of the Korean Confederation of Trade Unions, walked off the job and joined the strike.

The organizers said they will start off by blocking the entries to major logistics hubs in the Seoul metropolitan area and other key regions, including Busan in the southeast and Gwangyang in the southwest.

The truckers have demanded the government extend a freight rate system guaranteeing basic wages amid soaring fuel costs.
