When I was affected, they sent a meeting notice for a required meeting in a conference room the next morning.
There were 6 - 7 other people there at the same time.
Some exec read the script and an HR person was there as witness, I guess, and to facilitate paperwork.
At another site I worked closely with, two meeting notices went out: Room A was OK, while Room B was bye-bye!
