①A worker dispatching provider must not create differences between the base pay, bonuses, and other treatment of the dispatched workers it employs and the corresponding treatment of regular workers that the client employs that are found to be unreasonable in consideration of the circumstances, including the dispatched workers' and regular workers' job descriptions and the scope of changes in their job descriptions and assignment, that are found to be appropriate in light of the nature of the treatment and the purpose of treating workers in that way.

②A worker dispatching provider must not, without legitimate grounds, subject a dispatched worker to treatment that is disadvantageous in terms of base pay, bonuses, or other such treatment when compared to the treatment accorded to a regular worker employed by the client, if the dispatched worker's job description is the same as that of the regular worker, and their job description and assignment throughout the entire period until the end of their assigned work for the client are expected, in light of the worker dispatching contract, the client's customary practices, and other such circumstances, to be changed within the same scope as the job description and assignment of the regular worker throughout the entire period until the end of their employment relationship with the client.
