Why does this payslip matter right now? A Thai worker's '₩4.02 million payslip' has set social media alight both in Korea and abroad, raising fundamental questions about the realities of migrant labor in Korea and the structure of manufacturing wages.

TL;DR

• Thai factory worker's average monthly wage: ₩620,000 → One month at a Korean factory: ₩4,020,000 (including overtime and holiday pay)
• Worker A worked 31 days straight in August of last year without a single day off, receiving a gross salary of ₩4,027,045
• Base pay of ₩2.09 million + Saturday/holiday allowances of ₩840,000 + 46 hours of overtime pay + early-start allowances, etc.
• Net take-home pay nearly double the monthly equivalent of Korea's 2026 minimum wage (₩10,030/hour, approx. ₩2.09 million for a 40-hour week)
• As migrant worker numbers grow, the appeal of 'high-wage Korea' and the shadow of an 'overwork structure' are thrown into simultaneous relief

1. The Facts: How Was the ₩4.02 Million Payslip Generated?

Worker A, a Thai man, disclosed a payslip on social media showing a gross total salary of ₩4,027,045 earned while working at a domestic manufacturing plant in August of last year. Breaking it down:

Worker A stated on social media: "I didn't take a single day off (31 days of full attendance)."

2. The Spread Mechanism: Why Did It Go Viral Now?

This post caught fire not simply because it was 'wage bragging,' but because Thai local communities and Korean online communities reacted simultaneously.

• Thai reaction: According to Thailand's National Statistical Office (NSO), the average monthly wage for Thai workers is approximately 15,565 baht (₩620,000), and Bangkok's minimum wage is around 9,300 baht (₩430,000). The fact that the Korean wage is 6–7 times the Thai average was received as a shock.
• Korean reaction: Alongside sympathy for the grueling conditions — '31 days with no days off' and '46 hours of overtime' — a shared sentiment of "still have to earn a living" emerged.
• Media pickup: Major outlets including Hankyung, Money Today, and Yonhap News reported in quick succession, driving the topic to the top of real-time search charts.

3. Context and Background: The Structure of Migrant Labor in Korean Manufacturing

The number of foreign workers in Korea surpassed approximately 1 million as of 2025, filling so-called 3D (Dirty, Dangerous, Demanding) jobs in manufacturing, agriculture, and services that domestic workers tend to avoid.

"The base pay itself is at minimum-wage level, but when overtime and holiday work pile up, earning ₩2–4 million or more is possible. The problem is that this 'possibility' presupposes overwork." — Migrant labor expert

• The majority hold E-9 Non-Professional Employment visas, and since changing employers is difficult, it is structurally hard to refuse even in overwork environments.
• Under the Employment Permit System (EPS), workers from 16 countries including Thailand, Vietnam, Cambodia, and Indonesia are legally employed.
• Korea's 2026 minimum wage: ₩10,030/hour → Monthly equivalent of approx. ₩2.09 million (based on a 40-hour week)

4. Five Key Questions

① High Wages or Overwork Exploitation?

₩4.02 million is undeniably a high wage by Thai standards. However, 31 days of non-stop work + 46 hours of overtime may constitute a violation of Korea's Labor Standards Act (52-hour weekly limit). Migrant workers face structural vulnerabilities that make it difficult to report such violations.

② Are Korean Manufacturing Wages Actually Attractive?

Looking at base pay alone, ₩2.09 million is 3–4 times that of Southeast Asia. However, real purchasing power adjusted for Korea's cost of living and housing costs may be lower than expected. Migrant workers come to Korea for the 'ability to save,' not for domestic spending power.

③ Do They Compete with Domestic Jobs?

The sectors that migrant workers primarily fill are manufacturing and agriculture that domestic workers avoid. Analysis generally favors the view that this functions more as a supplement to labor shortages than as direct wage competition.

④ Will This Trend Continue?

With Korea's working-age population declining due to low birth rates and aging, demand for migrant labor is expected to increase further. The government expands quotas for foreign seasonal workers and non-professional employment visas every year.

⑤ What Does This Payslip Reveal About Korean Society?

The structure that requires 'working 31 days straight to earn ₩4 million' overlaps not only with the reality of foreign workers but also with the reality of young Korean domestic workers. Calls for a rethink of the manufacturing ecosystem — in which overwork has become the norm — are growing louder.

5. Outlook: Where Does This Debate Go?

• In the short term, it will likely be consumed as social media buzz, but it has the potential to ignite legislative discussions on improving migrant worker treatment
• Civil society groups are expected to call for inspections into the real application of the '52-hour week' to foreign workers
• In Southeast Asia, the 'Korean Dream' is likely to spread again → Intensified competition for E-9 visas expected
• In the medium to long term, a need for a comprehensive review of immigration policy as a whole will emerge
