You can switch teams off and on according to your needs. The practical case could be a collective vacation or reorganization.
Switching off a whole organization or a division will switch off and on all subunits as well. But you can also switch off and on the subunits individually according to the need.
Switching a unit off means that the employees of that unit do not receive any questions. The managers continue receiving questions as they report to the team above.
Switching a team off is applied from the next day (D+1).
Switching a team on is applied on the same day (D+0).
