If a person violating this Act is an agent, employee, or other staff member who was acting on behalf of the person in control of the business in connection with a particular that concerns a worker at that business, the fine under the relevant Article is also assessed against the person in control of the business; provided, however, that this does not apply if the person in control of the business has taken the necessary measures to prevent the violation (if the person in control of the business is a juridical person, the representative thereof is deemed to be the person in control of the business; and if the person in control of the business is a minor or an adult ward without the same legal capacity to act as an adult in connection with that business, the statutory representative thereof is deemed person in control of the business (if the statutory representative is a juridical person, the representative thereof). The same applies hereinafter in this Article).
