I voluntarily left a well-known tech company after the 1 year stock option vesting cliff. When notifying the company that I wanted to exercise my options (within the 90 day window) they informed me that they were exercising their right to claw back and repurchase those options.<p>I'm curious if this has happened to others in the tech industry. What recourse do employees have in a situation like this? What should one look out for to avoid this in the future?
