副業 and 兼業: A Side Job, Combined Activities, and Rule Checks
Compare photography on days off with a family's farm and restaurant. Separate checking company rules or permitted scope from individual approval or starting combined work, while preserving translation overlap.
Photography as a side job and checking whether it is allowed
副業 (ふくぎょう) means a side job or second job. 「休日に写真を撮る仕事を副業にしている。」 — “I take photographs as a side job on my days off.” The speaker treats photography on days off as a side job.
「会社の規則で副業が認められているか確認した。」 — “I checked whether side jobs were permitted under company rules.” The checked issue is whether side jobs are allowed by company rules. The check alone does not supply an affirmative result or a report of starting one.
Combined farming and restaurant work and permitted scope
兼業 (けんぎょう) means combined work or dual employment, and its English meanings also include side job. 「農業と飲食店を兼業する家族に話を聞いた。」 — “We spoke with a family that runs both a farm and a restaurant.” The family spoken with runs the farm and restaurant. Do not turn the person who heard their account into the operator of both activities.
「会社の規則で認められる兼業の範囲を確認した。」 — “I checked the range of side jobs permitted by company rules.” The speaker checked the range allowed by company rules. Checking that range does not report individual approval or completed commencement of combined work.
Overlapping translations and different focuses
副業 focuses on subsidiary work here; 兼業 focuses on doing activities together, such as farming and running a restaurant. Translations such as side job overlap rather than creating exclusive categories.
Second job and dual employment do not create a mechanical rule about the number of employers. Preserve the stated activities and the scope checked without declaring the actual rules of any real company.
How does photography on days off as 副業 differ in focus from the family's combined farming and restaurant work as 兼業?
Show the answer and why
The photography 副業 focuses on the work's secondary position; the family's 兼業 focuses on doing farming and restaurant work together. Side-job translations can overlap without making the terms exclusive categories. The separate company-rule examples report checking whether side jobs are allowed or what range is allowed, rather than individual approval or the start of another job.
