Er no, as employees they're also paid partly in stock options (RSUs?). They're literal shareholders in the company, they have a say in how it's run.

And I don't know about you, but many people don't just run away when faced with a difficult situation - they face it head on and try to improve it.

Furthermore, if I spent years of my life contributing to a mission that I believe in, giving a company my best work, I'm not going to just walk away because of the actions of a single entitled individual, no matter how rich he is.

So employees compensated by their employer via stock options are entitled to attempt to sabotage their company’s leadership from within without repercussion?

They're not trying to sabotage anything. They're asking for SpaceX to disassociate itself from statements made by Musk, an individual, which harm the company.
