For those who are curious this union drive was really started by extreme incompetence from upper management. The former CEO hired ineffective status-seekers (including the current CEO) into many positions of power which created a super toxic environment. Accountability for internal problems has been extremely low. The "Always Punch Nazis" controversy was just the straw that broke the camel's back.

People in the bay area may not understand that most people working at Kickstarter truly believe in the company's mission. The money is not great and we've been willing to accept that to feel like we're making a positive change in the world. Unfortunately upper management has used this (as well as Kickstarter's reputation) as a bargaining chip to treat employees poorly.
