Is the commission requested by the employee on the products considered legitimate brokerage, a stipulated fee, or illicitly consuming wealth?

This employee, by requesting a commission and adding it to the prices paid by his company, is betraying a trust and consuming wealth unjustly. This is because he is an agent for his company and is obligated to act in its best interest. It is not permissible for him to take a commission on the company's purchases without its permission. It is also not permissible for the questioner to assist him in this falsehood or to deliver to him this unlawful money, which rightfully belongs to the company.
