It is pretty clear that the Yoon administration has declared war on the violent and pro-North Korean KCTU. Here is the latest front he has opened up on them:

Eradicating illegal practices at construction sites has been a central part of labor reform, one of the Yoon administration’s top three areas of reform along with education and pensions, the presidential office said.
Since late last year, the land ministry has run a designated team to respond to violence at construction sites while the police have operated a 200-day special crackdown period, it added.
The government’s hard-line stance comes as construction unions affiliated with the country’s two major umbrella labor organizations — the Korean Confederation of Trade Unions and the Federation of Korean Trade Unions — have been accused of coercing employers to hire their union members for construction jobs.
“Militant labor unions with vested rights continue to overtly carry out illegal actions at construction sites, such as demanding money and goods, forcing hiring and obstructing construction,” Yoon said during the Cabinet meeting.
“As a result, workers are losing their jobs and construction is being poorly done. The damage is being passed on to the people, with delays in the opening of new elementary schools and move-ins to new apartments,” he said.
