CEO work can only be done in a public session in GTA V, but it's such a pain in a server with dozens of other players all trying to sabotage your organization.
The trick is to get yourself into a "private" public session. To do this, go to your office in GTA V, then disconnect your Ethernet cable for about ten seconds, then plug it back in. That's not quite long enough to time-out, but just long enough to boot everyone from your session. You'll see on the left side of your screen that everyone starts to "leave" your lobby, but in reality, Rockstar is just placing you in your own new lobby.
You can have your friends join this new lobby, and if a rondo happens to join your lobby, all it takes is three votes to kick them out of it.
