Although there seems to be a trend toward allowing side hustle…
According to the “Questionnaire Survey on Side Jobs and Double Jobs” conducted by Adecco, Inc., the results are as follows.
More than 40% of the companies allow ” side hustles/double jobs”. On the other hand, more than half of the companies still do not allow “side hustles/double jobs”.
Less than 20% of companies that currently prohibit “second and multiple jobs” are considering allowing it in the future.
Less than 30% of companies “accept” the employment of people with second or multiple jobs, and more than half “do not plan to accept” them.
In this survey, side hustles are defined as “sub-jobs done in between main jobs” and multiple jobs are defined as “doing multiple jobs as one’s main job (dual jobs), but in this article, they are collectively referred to as side hustles, etc.
This survey was conducted on managers and section chiefs working for listed companies, so the trend is not the same for other demographics, but it seems that they are gradually moving toward allowing side hustles.

Do you still allow side hustles?
There are many aspects of side hustles that need to be taken care of, such as understanding working hours (self-reporting of working hours, total rules, management based on the Ministry of Health, Labor and Welfare’s management model, etc.), the obligation to pay extra wages, and health management. In addition, if an employee of your company suffers a work-related injury that requires time off from work at a second job, it will naturally affect your company’s operations. For these reasons, as shown in the survey above, some companies, even listed ones, are reluctant to accept side hustles.
If you understand the issues related to side hustles, etc., and still want to consider allowing them, it is essential to have a written pledge with employees that they are obligated to devote themselves to their main business, including the obligation to report their working hours, and to have related employment regulations in place.
If we have a system where people are allowed to do side hustles under the service contract, this problem will be somewhat reduced. However, this may weaken the effectiveness of the system in increasing the attractiveness of the company, so it may be difficult to introduce such a system in the current situation. Even if you decide to adopt a system that allows for side hustles, etc., careful consideration will be necessary.
