If targeting "right to work" is the first step, then perhaps we can organize something around abolishing that. If abolishing is too difficult, then perhaps modifying it so that "right to work" only applies to companies that have less than $1 million but have safeguards in place to ensure fair layoff packages, but companies with more than $1 million must allow unions. That way, small companies don't have to worry about unions and when they're big enough, they'll have the money and the lawyers to deal with it.
Waiting is a loser's game. With another recession, the government will do just enough to keep people content, but not go that extra length to solidify those protections. With changing seats of power over time (re-elections), there's no guarantee that the next set of people in power won't dismantle protections... causing the cycle to repeat... causing us to wait for another recession... and so forth.
Honestly seems like it'd take another great recession with the focus put on employee rights for major changes to happen. Luckily with Obama leaving he is finally lending some helping hand to Unions by making companies disclose when the get advice from anti-union advisers [2]
