What is the ruling on taking monthly commissions and travel commissions for each individual, especially commissions for the travel of nurses, beauticians, and female doctors without a mahram? And what is the ruling on dealing with their travel without a mahram? And what is the evidence for that?

Working for this company is permissible if it does not involve assisting in anything forbidden, and if the wage is known and specified. The added commission is not part of the salary but rather a 'ju'l' (a stipulated reward for a specific task), and a 'ju'l' may be a percentage of the profit. There is no objection to the percentage if it comes from the company, unless the client agrees to it with the company's knowledge. It is not permissible to assist women who travel without a mahram (definition), nor to take money from them for doing so, because a woman's travel without a mahram is forbidden.
