When attempting to delete or reassign a Staff user as a Client, the Staff user may have Action Templates that they are the "Assignee" of or have other links that prevent their deletion. This is by design to prevent orphan objects and/or invalid templates or other entities.
The following dialogue will appear if attempting to delete a Staff user who is still an assignee of an Action Template...
To resolve this, find the Action Template(s) that has this Staff user set in the "Assigned to" field and select another Staff member or skillgroup then try deleting the Staff member again. If the same message appears then they need to be removed from other Action Templates also before they can be deleted.
