It’s a dick move for sure, but the clawback of unvested shares is vicious. Not possible to know the total worth without being privy to the employment contracts of those let go, but for a single senior employee of long tenure it might constitute a 6- or 7-figure rip-off. Depending on the number of staff let go, the amount of options each held and what their strike prices were, this layoff could potentially constitute a clawback of options that would have been worth tens or even hundreds of millions of dollars of Sony shares.
