It's simply what admins set their tag as (using /settag Working or /settag Manager) when they are busy or working. They aren't real gangs, simply tags. Think, like, in Capture The Flag, people have their tag set to "Red Team" or "Blue Team". Those are only temporary tags, not guilds.
CountrySide, I'm assuming. They probably take hold of the forts there, thus rewarding them hours.
I do hope they never just messed around on a base for around 80 Days.
