This idea that unions MUST be antithetical to the company or performance is silly. We have counterexamples on TV almost every day. Further, the idea that job insecurity is the best way to motivate people to perform also seems silly.
If you read the highlights, they're just asking for documentation on termination and disciplining. Not at all unreasonable.
You can prove anything from a false premise.
If you're talking about keeping 'high performers' in sales, that's what commission is for.
If you're talking about keeping 'high performers' in engineering, ... well, do you even need high performers? Due to the nature of their business, there are no challenging technical feats to accomplish. You really just need solid engineers to push the product and maintain the infrastructure.
"high performers" aren't going to be satisfied by Kickstarter's compensation at first place thus won't apply there.
Also good luck arguing to your boss you are a "high performer" in a company that has "progressive performance evaluation", by what measure?
This is a none issue.
High performers in tech do not have a problem with the heirs who own a majority of their corporation's stock telling them what to do, but are allergic to the people alongside them doing the work and creating the wealth from having input.
Do you know how hard it is to already weed out underperformers in large tech companies? I wouldn't be surprised if half of Kickstarter's engineers pumped out fewer than 3 PRs a week. Only the underperformers will choose to stay in the long run.
Ah yes. That always super meaningful metric of high performance - number of PRs. Doesn't matter what it is, if you can't solve it and push some code in less than two days, it's a clear indicator you're a terrible engineer.
