In SfB I can add a GROUP and the membership of that GROUP is centrally managed by the IT Dept. As staff leave or join the company they are deleted or added to the relevant GROUP. For GROUPS consisting of shift work staff I can easily check who is actually working at a particular time.This feature is missing from SfB. Creating a TEAM does not achieve the same result as I have to manage the TEAM and be aware when staff join/leave the company.
