Note: June 3, 2026 – This is an update to the May 31, 2026 article: Samsung Legal Challenges Pile Up as Donghaeng Delays Injunction, Main Union Restructures.

SEOUL – June 3, 2026 – Three days after the Donghaeng Labor Union announced it would delay filing its revised injunction, the minority union has formally submitted the request to the Suwon District Court. The move came on June 2, 2026, as a lawyer for the union confirmed the amended application seeking to suspend the effectiveness of the signed wage agreement. In a separate development, an activist shareholder campaign that had threatened a lawsuit has lost momentum following a 26% surge in Samsung Electronics’ stock price. Meanwhile, the main union has announced it will focus future negotiations on the semiconductor division, acknowledging it was “arrogant to think DS and DX could move together.”

The Essentials: Who, What, When, Where, Why, How (Last 48 Hours)

Who: The Donghaeng Labor Union (representing approximately 13,000 DX division workers); Samsung Electronics management; the main Samsung Electronics Labor Union (SELU); the Korea Shareholder Movement Headquarters; the Suwon District Court; and police investigating an alleged employee blacklist.

What: The Donghaeng Union filed an amended injunction to suspend the wage agreement. The shareholder campaign postponed its planned assembly and may not proceed with a lawsuit. The main union announced it will prioritize the semiconductor (DS) division in future negotiations. Police executed a third search warrant in the blacklist investigation.

When: The injunction was filed on June 2, 2026. The stock price surge occurred between May 20 and June 2, 2026. The main union’s semiconductor-focused strategy was announced on May 30, 2026. The police search took place on May 28-29, 2026.

Where: The injunction was filed with the Suwon District Court in Gyeonggi Province. The shareholder assembly was to be held in Seoul. The police search occurred at multiple unspecified locations.

Why (Immediate Cause): The Donghaeng Union seeks to nullify a bonus agreement that gives vastly larger rewards to chip division employees. The shareholder campaign lost support because the stock price surge reduced investor motivation to challenge the deal. The main union is responding to membership losses and internal dissent.

How (Mechanism): The Donghaeng Union filed a provisional injunction application under South Korea’s Labor Union Act. The shareholder campaign uses a petition-based mechanism. The main union is restructuring internally without court approval. Police act under criminal procedure laws for non-complaint-based offenses.

Specific Updates in the Last 48 Hours (June 2–3, 2026)

1. Donghaeng Union Files Amended Injunction with Suwon District Court

On June 2, 2026, a lawyer for the Donghaeng Labor Union confirmed that the union had filed its amended injunction application. The filing requests that the court suspend the effectiveness of the wage agreement signed on May 27, 2026.

Background on the Dispute: The wage agreement provides vastly different bonuses by division. Approximately 78,000 employees in the semiconductor (DS) division are eligible for bonuses worth roughly $330,000 each. Employees in other divisions, including the DX division where many Donghaeng members work, are eligible for approximately 4,000 each. The Donghaeng Union argues that the majority union violated its duty of fair representation by excluding minority union members from bargaining.

Current Status: The signed wage agreement remains in full effect unless and until the court issues a ruling granting the injunction.

Legal Timeline: The Suwon District Court has already heard initial arguments from both sides at a May 29 hearing. Once the court reviews the amended filing, a ruling is expected within approximately one month.

What This Means: The legal challenge is now formally active. The court’s decision will determine whether the wage agreement is temporarily suspended pending further proceedings.

2. Shareholder Campaign Loses Momentum After 26% Stock Surge

The Korea Shareholder Movement Headquarters, an activist shareholder group, has seen its planned legal challenge “waned considerably” due to a sharp rise in Samsung Electronics’ stock price. Between the signing of the wage agreement on May 20 and June 2, 2026, the company’s share price surged by 26%.

Campaign Status: A shareholder assembly that had been scheduled for June 6, 2026, has been postponed. The group’s leader stated, “Without shareholder support, we will not proceed” with lawsuits.

Legal Basis (If Filed): The group intended to argue under the South Korean Commercial Act that the wage agreement causes financial harm to shareholders due to the bonus disparity and potential legal liabilities from the exclusion of the Donghaeng Union from bargaining.

What This Means: The threat of a shareholder lawsuit has significantly diminished. The surge in stock price suggests that the broader investor community views the wage agreement as favorable or neutral for the company’s value.

3. Main Union Announces Semiconductor-First Strategy

In a significant shift, the main Samsung Electronics Labor Union (SELU) has announced it will focus its future bargaining efforts on the semiconductor (DS) division. Union chairman Choi Seung-ho stated that 95% of SELU’s members work in the DS division.

Admission of Past Error: Chairman Choi acknowledged that it was “arrogant to think DS and DX could move together,” recognizing that the semiconductor division and the device (DX) division have fundamentally different priorities regarding bonuses and working conditions.

Warning to DX Division Workers: Choi warned that if the DX division negotiates separately, its wage increase would likely be “less than 2%.” This confirms the “two-track bargaining” system that was announced on May 30, 2026, where DS and DX division issues will be negotiated separately in future rounds.

Current Status: The restructuring has been announced but not yet implemented. The next wage bargaining round is expected in early 2027.

What This Means: The main union is effectively conceding that it cannot represent both divisions’ interests simultaneously. DX division workers who opposed the 2026 agreement may have diminished bargaining power through the main union in future rounds.

4. Police Execute Third Search Warrant in Blacklist Probe

Independent of the labor dispute, police have continued their investigation into allegations that Samsung Electronics maintained an employee “blacklist.” On May 28-29, 2026, investigators executed a third search and seizure, securing computer data from individuals with irregular access records and those implicated in leaking personal information.

Legal Status: Police have made clear that this investigation will proceed regardless of any agreement between Samsung and the unions. The offenses under investigation are not “complaint-based,” meaning they do not require the company’s cooperation to pursue.

What This Means: Samsung faces ongoing legal pressure from a criminal investigation that is entirely separate from the labor dispute and the shareholder campaign. The outcome of this probe could result in independent penalties or findings of misconduct.

Why This Matters (Updated for June 3)

The past 48 hours have fundamentally altered the landscape of the Samsung labor dispute in three ways.

For the legal challenge: The Donghaeng Union has moved from delay to action. The injunction is now formally before the Suwon District Court. The court’s ruling, expected in approximately one month, will determine whether the wage agreement is suspended.

For the shareholder threat: The 26% surge in Samsung’s stock price has neutralized the activist shareholder campaign. Investors are signaling approval of the wage agreement, removing a key source of pressure on management and the main union.

For the main union: By announcing a semiconductor-first strategy and admitting it was “arrogant” to think it could represent both divisions, the main union has effectively conceded that DX division workers require separate representation. This validates the very complaint that drove workers to the minority union.

For Samsung employees: DX division workers who opposed the wage agreement now face a diminished prospect of representation through the main union, which has explicitly stated it will focus on the DS division where 95% of its members work.

For South Korean labor law: The court’s handling of the duty of fair representation argument will set an important precedent regardless of the outcome. The case addresses whether a majority union can exclude a minority union from bargaining and what remedies are available to excluded unions.
