The Los Angeles Times online opinion page has a piece on John Ridley's decision to go financial core. (See my post here for an explanation of what fi-core means.)
Ridley's decision has understandably caused quite the furor: check out the HuffPost, NY Times, NPR, and the Strike Hawk Blog.
I'm not taking a position on this one; I'm not a Guild member and don't feel comfortable getting between a member and his union. But I will say this: if a large group of members opted to go fi-core, it would weaken the Guild.
So, I hope if an organized group forms to do this, that they'll go to the Guild leadership first and try to exercise their leverage (regarding negotiating tactics), before taking this drastic step.
