South Korea's labor inspectors will take full independent control of investigations — from initiation to closure — starting in October, following the abolition of prosecutors' special judicial police oversight authority. The Ministry of Employment and Labor plans to establish a dedicated training center next year and, over the longer term, build a full training institute to sharpen inspectors' investigative expertise.

According to the ministry, labor inspectors will from October handle cases involving wage theft, violations of the Occupational Safety and Health Act, and unfair labor practices without direction from prosecutors. The planned training center will provide specialized instruction in criminal procedure law, investigative techniques and evidence-collection protocols. Officials are considering placing the facility outside Seoul, in a regional location.

Minister of Employment and Labor Kim Young-hoon told reporters recently that "the prosecutor's most important role has been deciding whether to open or close an investigation," adding that "the system has now shifted so that labor inspectors make those calls themselves, and branch office directors must take on the role prosecutors once played." He said the ministry plans to launch a 24-person training center next year and expand it into a full training institute over time.

The ministry's push to establish a dedicated training institution reflects the need to build investigative capacity commensurate with the expanded authority. Labor inspectors have until now handled cases on the assumption that prosecutors would provide oversight and supplementary investigation, but going forward they must independently judge everything from case initiation and evidence collection to whether to refer a case for indictment. Proper handling of criminal procedure has become a central challenge, particularly because evidence obtained in violation of the Code of Criminal Procedure may be ruled inadmissible.

Calls for a new educational foundation have been raised consistently from the field. The ministry added 1,000 inspectors last year — 700 labor standards inspectors and 300 industrial safety inspectors — and is pursuing further increases this year, yet no institution dedicated solely to training labor inspectors has ever existed. Critics have long noted that the structure requiring inspectors to simultaneously handle workplace supervision, administrative guidance and industrial accident investigations left little room for systematic training in criminal procedure and investigative practice.

New labor inspectors have pointed out that their experience in criminal procedure lags behind their expertise in industrial safety and labor standards, and that existing training programs, centered on manufacturing and construction, fall short when it comes to handling labor cases across a wider range of industries.

The operational structure that requires a limited workforce to carry out supervision, investigation and guidance simultaneously is also seen as an area needing reform under the new independent investigative regime. Simply expanding headcount is not enough — specialized training, systematic mentoring and stronger professional development must accompany any increase.

A local labor inspector system set to take effect in December is adding further urgency to the need for a professional training framework. Local government-affiliated labor inspectors will directly supervise and investigate violations of labor law — including wage theft, working conditions and industrial safety — making it increasingly important to establish consistent investigative and enforcement standards across both central and local government.

The ministry plans to use the training center to standardize investigative techniques, criminal procedure, inquiry methods and evidence management, and to eventually expand it into a full training institute responsible for training new inspectors and providing continuing education.
