Do you want to allow your employees to be associated with multiple Above Units and/or Units? Or should they be associated only with one Above Unit/Unit? It's up to you! You, as an academy admin, have the option to define if the employees will be able to be associated with more than one (Above) Units!
To do so, hover over Admin from the upper navigation menu, click on the Academy Settings option, go to the Advanced Settings of your academy and search for the Organizational Structure setting.
This setting allows you to associate users with multiple (Above) units.
If multiple (above) units associations is unchecked, then you (as well as any user with the Add/ Remove Units permission enabled) will not have the option to add more than one (Above) Units to your academy members.
However, an extra option will be available in this case, which will allow you to move users from one (Above) Unit to another. Moreover, you will be able to choose if you want to retain the job for this user or not.
Please note: If the employees were allowed to be associated with multiple (Above) Units up to now and you want to disable the multiple (Above) Units associations for your academy from now on, please contact us (firstname.lastname@example.org) in order to clear the current multiple (Above) Unit associations (Users that have more than one (Above) Units tied to their account).
