Advocating for better working conditions. For example (not saying that these are specific to Kickstarter, I don't know that culture, but they do occur elsewhere in tech):

1) Better IP restrictions. Working on open source, side projects, etc.

2) Better treatment around oncall.

3) Limiting hours (no expectations of 60+ hour weeks)

4) Transparency in hiring, promotion, and review processes

5) Transparency in company performance and benefits decisions

6) Better benefits, particularly things like parental leave, vacation, and health care

7) A greater slice of the value that workers provide

8) Representation at the board level, or at least a democratically elected representative to the C-level

9) A representative during disagreements with the company (e.g. making it harder to be singled out/fired just because)

There are probably a bunch more, this is just what comes to mind off the top of my head.
