Factory Types in Korea That Can Reach 4 Million KRW Salary

Many workers aim to earn around 4 million KRW per month in South Korea, but this level of income only happens when multiple factors align. A combination of base salary, overtime, night shifts, and weekend work is essential. Without all these components, reaching that level under the E-9 system is extremely difficult.

Automotive parts manufacturing is one of the most stable sectors. Regions like Ulsan, Asan, and Changwon host factories with continuous demand. With consistent overtime and shift systems, workers can earn close to 4 million KRW monthly.

Plastic injection factories are also known for high earning potential. Machines operate 24 hours a day, creating constant demand for workers. Although tasks are relatively simple, the combination of overtime and night shifts significantly boosts income.

Steel and metal processing industries offer even higher earnings with additional hazard allowances. However, these jobs are physically demanding and require strong endurance. Shipyard subcontracting jobs provide the highest income potential but also come with the highest risk and difficulty level.

In conclusion, high salaries in Korea are driven by workload intensity rather than job titles. Factories that operate continuously, have strong demand, and provide consistent overtime are the key to reaching top income levels. Choosing the right industry and region is crucial for maximizing earnings.
