Unfair Labor Practice Lawyer | A worker's guide to recognizing retaliation and filing for remedy

Unfair Labor Practice | What Counts as an Unfair Labor Practice

The Trade Union and Labor Relations Adjustment Act lists specific categories of employer conduct that qualify as unfair labor practices (노동조합 및 노동관계조정법 제81조). Recognizing which category your situation falls under matters because it shapes what evidence you need and how the Labor Relations Commission will evaluate your claim.

Unfair Labor Practice | When Dismissal or Discipline Is Really About Union Activity

The most common worker complaint is being dismissed, transferred, or disciplined shortly after joining a union or taking part in organizing. Because employers rarely state the real reason openly, these cases usually turn on indirect evidence.

Timing as Circumstantial Evidence

A disciplinary action or transfer that closely follows union formation, a strike, or a worker's election as a union officer is often treated as suspicious timing by the Labor Relations Commission. Timing alone is rarely decisive, but combined with other facts it can shift the burden onto the employer to explain its reasoning.

Comparing Treatment of Similarly Situated Workers

If a non-union coworker with a similar record was not disciplined for comparable conduct, that discrepancy is one of the strongest pieces of evidence in these cases. Keeping records of how coworkers in similar positions were treated helps build this comparison.

Pretextual Reasons

Employers sometimes cite performance issues, restructuring, or rule violations that were never enforced before the union appeared. Whether the stated reason is genuine or a pretext is frequently the central factual dispute litigated before the Commission.

Unfair Labor Practice | Interference With Union Formation and Operation

Beyond individual retaliation, employers sometimes act to weaken a union as a whole — through surveillance, pressure on members to withdraw, or setting up a rival organization. These patterns are harder to prove individually but often appear together.

Pressure to Withdraw from the Union

Managers individually contacting employees to suggest they leave the union, or implying career consequences for staying, can constitute domination or interference under the Act (노동조합 및 노동관계조정법 제81조 제1항 제4호). Written messages, recordings, or witness accounts of such conversations are important.

Financial Support Used to Undermine Independence

Providing office space or funds to a union is not automatically unlawful, but doing so in a way that makes the union financially dependent on management can be scrutinized as interference. The distinction usually depends on whether the support compromises the union's actual independence in decision-making.

Refusal to Bargain Without Justifiable Reason

When an employer repeatedly postpones bargaining sessions, sends low-level representatives without authority to negotiate, or refuses to provide information necessary for bargaining, this pattern can support a finding of bad-faith refusal to bargain (노동조합 및 노동관계조정법 제81조 제1항 제3호).

Unfair Labor Practice | What Evidence Actually Moves These Cases

Because unfair labor practice cases rarely involve a written admission from the employer, workers need to actively preserve evidence from the moment they suspect retaliation. What you gather in the first few weeks often determines the outcome.

Contemporaneous Records

Notes made close to the time of an incident — dates, who was present, what was said — carry more weight than a reconstruction written months later. Emails, internal messenger logs, and meeting minutes are often more persuasive than personal recollection alone.

Union Activity Records

Keeping a record of your own union role and activities (meeting attendance, officer positions, statements made in negotiations) helps establish the link the Commission will look for between your activity and the employer's response.

Statutory Filing Deadline

An application for remedy must be filed with the Labor Relations Commission within three months of the date the unfair labor practice occurred (노동조합 및 노동관계조정법 제82조 제2항). Missing this window generally forecloses the administrative remedy route, so early consultation matters even before all evidence is fully organized.
