Kickstarter recently voted for a union and was able to negotiate excellent terms for their layoffs.

Check out their website here: https://kickstarterunited.org/

On another note, unions are a wonderful idea for increasing worker power. I don't understand how people expect others to care about democracy, voting, etc. when we're stuck in a dictatorship 8 hours a day at work. Unions make the workplace more democratic, which will overall make people care more about democracy in general, IMO.
