South Korean media estimates participation could exceed 50,000 workers.

Negotiations between Samsung Electronics’ labour union and management over wage increases and the removal of bonus caps have collapsed, with the union saying it will proceed with its planned 18-day strike starting 21 May 2026.

According to Yonhap News Agency, both sides held two rounds of mediation on 11 and 12 May under the Ministry of Employment and Labor. The final session lasted 17 hours – from 10am on 12 May to 3am the following day – but ultimately failed to reach an agreement.

As reported, the union and management have serious disagreements over performance bonuses amidst the company's record earnings during the global artificial intelligence boom. The union has called on Samsung Electronics to scrap the current bonus cap, allocate 15% of operating profit towards performance bonuses, and formalise this clause within employment contracts.

Management, however, has reproposed allocating 10% of operating profit as bonuses, alongside a one-off special compensation package that it said exceeds industry standards. It also maintained that the union’s demands would be “unsustainable in the long term”.

The Korea Times quoted the union leader saying that the management had not meaningfully responded to its demands, and that no further talks are being considered ahead of the planned strike.

To date, around 41,000 union members have reportedly indicated their willingness to participate in the strike. With the breakdown of negotiations, South Korean media estimate total participation could exceed 50,000 workers – raising concerns over potential losses of up to 40tn won. Longer term, disruptions could result in customer attrition and supply chain strain.

Samsung Electronics has expressed regret over the breakdown in talks, stating it will continue to engage with the union in an effort to avoid the worst-case scenario.

South Korean Finance Minister, Koo Yun-cheol, also described the failure to reach an agreement as “deeply regrettable”, emphasising that “a strike must be avoided at all costs” and added that the government would “provide unwavering support until the very end”.

It is reported that the South Korean government may consider invoking an “emergency adjustment of industrial action”, which would suspend industrial actions for up to 30 days if they are deemed likely to harm the national economy or endanger citizens’ daily lives.
