Beginning today, a number of the country's truck drivers are going on a general strike for three days.
The delivery workers' union, under the Korean Confederation of Trade Unions, is calling for an extension of the Safe Rates system.
The transport ministry introduced the system in 2020, which guarantees minimum freight rates for trucking business operators delivering containers and cement.
The system is set to expire next year.
The union wants the Safe Rate system to be extended further to protect drivers from unsafe working conditions, such as longer hours.
With roughly five percent of the country's truck drivers in the union, the strike is not expected to have critical impact.
However, many container and cement truck drivers are members, which could affect transportation of those items.
