South Korean President Lee Jae Myung on Thursday, 30 April cautioned that excessive demands by unionised workers risk harming not just companies but fellow labourers themselves, calling for greater responsibility from labour organisations at a critical juncture for the country's industrial sector. His remarks, delivered during a meeting with senior aides at Cheong Wa Dae in Seoul, came directly ahead of Labour Day and amid a looming strike threat at Samsung Electronics.

What the President Said

"While companies should treat workers as valuable partners in corporate management, workers and labour unions must also have a sense of responsibility," Lee said, according to Yonhap News Agency. He went further, warning that unions perceived as making unfair or self-serving demands could face public backlash — damage that would ripple beyond the unions themselves. "If certain labour organisations face public outcry for excessive or unfair, self-serving demands, it would harm not only the unions themselves but other workers as well," he said, urging solidarity with fellow labourers.

Lee also tied his appeal to the broader disruption brought on by artificial intelligence. "At a time when the artificial intelligence transition is exposing the labour and industrial sectors to a fundamental change, there is a need for a spirit of coexistence and cooperation to overcome this critical challenge," he noted.

The Samsung Strike Threat

The immediate backdrop to Lee's remarks is a threatened 18-day general strike by a major labour union at Samsung Electronics Co., set to begin on 21 May. The union is demanding high bonuses proportionate to the company's record-high revenue. The timing is particularly sensitive: Samsung on Thursday reported that its first-quarter net profit surged more than fivefold to 47.22 trillion won, up from 8.22 trillion won a year earlier, driven by robust demand for high-end memory chips used in artificial intelligence (AI) applications.

Some analysts predict operating losses could reach as high as 10 trillion won (approximately USD 673.6 million) if the strike proceeds as planned — a figure that underscores the high stakes for one of South Korea's most strategically important corporations.

Labour Day and Broader Economic Concerns

Lee marked this year's first observance of Labour Day on Friday, 1 May as a statutory holiday, stressing the need for greater efforts to reduce labour market disparities and improve workplace safety. The designation of Labour Day as a statutory holiday is itself a symbolic gesture toward workers' rights, even as the president urged restraint from union leadership.

Separately, Lee flagged a macroeconomic concern: a sharp rise in producer prices last month that he warned could feed into consumer price increases within one to two months. He called on officials to make all-out efforts to stabilise consumer prices, identifying agricultural, livestock, and fishery products as well as logistics costs as areas requiring more targeted price stabilisation measures.

Why This Moment Matters

Lee's dual message — solidarity with workers, but accountability from unions — reflects the tightrope South Korea's new leadership is walking. The country's export-driven economy is navigating AI-era industrial transformation while managing domestic inflationary pressure and high-profile labour disputes at flagship conglomerates. Notably, this is not the first time Samsung has faced major union action; a 2024 strike at the company drew significant attention, signalling that labour tensions at South Korea's largest tech firm are becoming a structural concern rather than an isolated episode. How the Samsung union and management respond in the coming weeks will be closely watched as a bellwether for broader industrial relations in the country.
