Side-Job Bans and Side-Job (N-Job) Policies · Limits of Side-Job Restrictions in Rules of Employment
Moonlighting and Side-Job Policy
What is a side-job ban?
- Outside working hours, activities are generally free
- Competing work, misuse of materials, and use of job title are valid grounds for restriction
- A new reporting duty may count as a disadvantageous change
What a well-built side-job policy changes is the basis for discipline. A company with only a one-line 'no side jobs' clause cannot explain what harm an employee's YouTube channel caused, so any discipline ends up invalid. Activity outside working hours is, as a rule, the employee's own freedom. The company can restrict it only when it interferes with the employee's work, competes with the company, or damages the company's credibility. A blanket ban can itself be void, so replace it with a restriction clause that states its grounds.
Design the policy in three layers. The first is the principle of permission and the grounds for prohibition: bar working for a competitor, using company materials or client information, doing the work during working hours, and using the company name or job title. The second is a reporting or approval system. An approval system must also state the criteria on which the company will refuse. A reporting system only asks employees to disclose the fact, which keeps the management burden low but requires criteria for judging cases after the fact. The third is the level of discipline for violations. Also keep in mind that the four major social insurances are enrolled twice when someone works as an employee at another workplace, while employment insurance covers only the main workplace, so notices from the insurance agencies are often how a company learns about a side job.
This topic matters to HR and L&D managers because more in-house instructors and professionals now teach, write, and consult outside the company. Using company training materials in outside lectures, or running paid courses under a company job title, can violate a side-job ban. On the other hand, outside teaching experience can raise the quality of in-house training, so many companies allow side jobs with prior notification while restricting the use of materials and job titles.
Where practice goes wrong is in carrying civil-servant standards over wholesale. The ban on civil servants holding for-profit second jobs rests on the Civil Servant Act, so imposing the same level of restriction on a private company is unlikely to be upheld. Relaxing a blanket ban favors employees, but adding a new reporting duty or a new ground for discipline may count as a change to their disadvantage, so you need to follow the amendment procedure for your rules of employment. When a worker overworks on a side job and causes an accident in their main job, determining accountability and handling workers’ compensation both get complicated, so check the latest Ministry of Employment and Labor guidance on whether working hours are aggregated and on health-management standards.

In Korea, the benchmark is case law in which courts have narrowly construed rules of employment that ban all activity outside working hours. As platform work and content creation have grown, redesigning these rules has become a priority, along with the term 'N-job.'
Consider a hypothetical case. Company A, an education content firm with 290 employees, had only one line in its rules of employment: 'Employees may not engage in any other occupation without company permission.' This September, it came to light that an in-house instructor was posting lecture videos on a personal YouTube channel on weekends. When the channel passed 20,000 subscribers, one executive demanded disciplinary action, and the company took a fresh look at the entire policy.
- The HR director consulted a labor attorney and was told that discipline based on a one-line blanket ban would likely be invalid. They then asked the executive to 'start by writing down what harm the company actually suffered.'
- The investigation found that the instructor had not used company training materials or disclosed their job title, but two videos included the company's client cases without anonymizing them, so only that part became subject to a correction request.
- The HR team drafted a policy with four grounds for prohibition (competing work, misuse of materials, doing the work during working hours, and use of job title) plus a reporting requirement. Because a new reporting duty could count as a change that disadvantages employees, they held an information session and went through the majority-consent process.
- The training team ran a one-hour session for 12 in-house instructors and employees who give outside lectures, walking them through the reporting form and the rules on using materials and job titles. One instructor said, 'It's actually easier when you tell us where the line is instead of just giving permission.'
- Three months after rollout, 27 side jobs had been reported, and only one, teaching for a competitor, fell under the grounds for denial. The YouTube instructor revised two client case videos and carried on, with no disciplinary action.
