I don't really understand what it means to "join as individuals not as a group." The GA isn't a membership body, there is nothing to "join." If SEIU members wanted to participate in a GA, they would do so the same way anybody else would.
What SEIU participation would probably look like in practice is that they would organize a rally at Zucotti Park, a few hundred people would show up, and after it ended a greater or lesser number of the SEIU members would stick around for a greater or lesser amount of time.
We should be very enthusiastic about getting participation from labor, however. SEIU represents mostly low-paid staff, largely in hospitals and hotels, many of whom are immigrants, documented and undocumented. They run Jobs with Justice, one of the best social-justice labor campaigns in the US. And labor has the ability to mobilize real numbers on Wall Street if they want to, as when they put 20,000 people on Wall Street on May 12. The more labor participation, the better.

It should be made clear that if the SEIU "join" the movement, they join then as individuals and not as a group, since the GA has essentially ostracized every other group and avoided forming coalitions.
