As someone who's been both a union member and on the management side, it's frustrating when all sides don't realize that unions don't magically make money available to distribute to employees. There is certainly the argument that money needs to be distributed more equitably, but in a lot of cases (having seen this directly) there is simply not much money to move around.
Certainly, I'd love it if Google's never-ending money spigot was available to all.
