A Practical Guide for Foreigners Navigating Side Job(“겸직” ) Rules
As Korea’s work culture becomes more flexible, more employees—locals and foreigners alike—are exploring extra income and creative opportunities. Influencer activities on Instagram or TikTok, online lectures, writing projects, rental property management, delivery side gigs, and even part-time driving have all become increasingly common. It’s no surprise that many foreign professionals in Korea also want to model, appear on YouTube, or take freelance jobs on weekends.
But here’s the important part: not every company allows side jobs, and not every restriction is legally valid. Understanding how Korean law views “겸직” (dual employment or side job) helps you protect both your career and your freedom.
1. Korean Companies Commonly Restrict Side Jobs—But Not Absolutely
Many employers are concerned that outside work could:
- Reduce the employee’s performance or rest hours
- Create conflicts of interest
- Risk misuse of trade secrets
- Damage the company’s reputation
Because of this, Korean companies often include “no side job” clauses in:
- Employment contracts
- Rules of Employment (ROE)
Some even list “unauthorized side work” as a disciplinary ground, leading to warnings, suspension, or even dismissal. This is why employees—especially foreigners—often assume that side jobs are strictly banned.
But Korean law takes a more balanced approach.
A rule prohibiting all types of outside work does not become valid simply because it appears in company regulations.
2. Courts Say: Your Personal Time Is Your Time
A key principle in Korean labor law is that employees must work faithfully during working hours, but after work, the time belongs to the individual.
The Seoul High Court has explicitly stated:
- A full-time worker’s off-duty side activities fall within personal freedom.
- Companies cannot impose blanket, all-encompassing bans on outside work.
- Broad prohibitions may violate constitutional freedoms such as:
- Freedom of occupation (헌법 제15조)
- Right to privacy (헌법 제17조)
(Seoul High Court, 2002. 7. 4., 2001누13098)
In other words, even if a company rule states “No employee shall engage in any outside work,” the company cannot punish an employee unless the specific side job actually threatens business interests or harms job performance.
This is especially important for foreigners who take part in modeling, content creation, or lecture activities that have nothing to do with their employer’s business.
3. Even Government Employees Aren’t Fully Banned from Side Jobs
Public servants in Korea face stricter standards than private-sector workers, yet even they are only limited in specific situations—such as when a side job:
- Reduces job efficiency
- Improperly influences public duties
- Creates interests that conflict with the state
- Harms the reputation of the government
(National Public Officials Service Rules, Art. 25)
This shows that Korea does not prohibit side jobs simply for the sake of prohibition. Restrictions must be reasonable, necessary, and narrowly tailored.
4. When Companies Can Legally Restrict Side Jobs
Private companies may discipline an employee only when the side job creates a real, concrete problem, such as:
- Competing with the employer
- Using confidential business information
- Causing physical exhaustion and performance decline
- Damaging the company’s brand or credibility
- Interfering with teamwork or attendance
- Violating immigration restrictions (very important for foreigners on E-7, D-2, H-1, etc.)
If a side activity is unrelated, harmless, and done outside working hours, Korean legal precedents strongly protect the employee’s freedom.
5. What This Means for Foreigners Working in Korea
For many expats, Korea is a place full of new chances—TV gigs, runway shows, K-beauty collaborations, freelance consulting, voice acting, and more. Legally, these activities are often possible, as long as they don’t harm your primary job and your visa allows them.
But to stay safe:
- Read your ROE and employment contract carefully.
- Confirm whether prior approval is required.
- Make sure your side activity is unrelated to your employer’s business.
- Keep clear documentation of approvals or notifications.
- Be mindful of immigration rules regarding additional paid work.
6. Why Companies Should Set Clear Standards
As career paths diversify and employee expectations shift, side jobs will only continue to grow. To minimize disputes, companies should:
- Define the standards for side-job approval
- Apply the rules consistently
- Communicate the regulations clearly to employees
- Keep written records of decisions and approvals
- Ensure their ROE aligns with legal principles and constitutional freedoms
With a transparent system, companies can protect legitimate business interests without infringing on an employee’s right to build a broader career.
Final Thoughts
Side jobs are now a natural part of Korean work culture, especially for globally minded employees. Korean law recognizes that people can have multiple talents and ambitions—and it protects workers from overly restrictive company rules.
For foreigners navigating Korea’s evolving job market, the takeaway is simple:
Your ability to pursue side opportunities is broader than you might think, as long as you approach it wisely and understand the rules.
