Oh$,$ I see.

So if we do use our main branch as a hub, how will employees at the new location connect to it$?$

Employees at the new location will have to go to one person at the branch who will log them in when they report to work and log them out at the end of their shift.

Employees can log in from anywhere using their Facebook logins$.$

The employees will log in through a VPN which is a virtual private network.
