FWIW, that is not how all agencies operate, unless they are under a contractual obligation.

For example, some agencies only limit themselves to not representing a previously placed candidate if they are still the role where they were placed by the agency. Outside of that, if a candidate wants to move from one client company to another, the agency may even act as a catalyst, especially if the candidate would be a great fit for the new role.

I wonder if they disclose such policies to companies they represent.

"We will do everything in our power to find you the employees you need, unless it might make one of our other clients unhappy."

This would be a disqualifying conflict of interest for a law firm.
