You can only be in one union, and a union can have up to 8 guilds. The guilds have to be lvl2 or higher in order to participate in a union.
In a union, you have the union chat where everyone in the union can read what the others are writing there, then there is the union icon similar to the guild icon.
Furthermore, the names of the union guilds appear green to you instead of blue.
