In Quickbooks, the users (employees) of the accountant are managed by the accountant section. According to this, it's possible to add or remove access to them for each client account.
If this exist, the tech support (chat) doesn't know...They tell I have to go in each client to remove (or add) access to my employee, so when there is a departure I have to retrace given access and remove one by one. A client list to check by user would be easier and time saving.
