At some point in the past, the best way we were aware of to allow employees to manage a client's Facebook business page was that we could ask the employee to add their work email address to their personal Facebook account and then the client could grant access by knowing the employee's work email address. Some drawbacks of this is that it still involved their personal Facebook account which ideally we wouldn't be asking people to have to do, and also there's the issue of reassigning permissions upon turnover.
Is this still the best way to approach this situation? Is there a better way wherein we don't have to ask an employee to use their own personal Facebook account, and also preferably where no permissions need to be reassigned if an employee's no longer with the company?
I understand that just because their personal account is used, doesn't mean that anyone viewing the page will see their personal account if the settings are done correctly - it's just that some employees feel uncomfortable using it, and there's a general business practice of not asking people to use their personal stuff.
The goal is to completely stay in compliance with the terms of service and not to do things that violate that, even if Facebook isn't catching/enforcing such violations.
