Well he already wasn’t listening to the employment lawyers since he fired the exec team for cause and took away their golden parachutes. He’ll be fighting those lawsuits for a while.
Dollars to donuts he's just using this to reduce their payouts, but unless he has pretty strong proof of wrongdoing, they'll all just settle. The execs will take home, say, $70 million instead of the ~$120 they were entitled (yeah, I'm crying a river on all sides) and everyone's happy.
Like the Twitter buyout itself, I think the execs have a strong legal right to the money. Why would they settle? Presumably they are already quite wealthy, and can wait out the courts.
Well, there’s laws for the procedure of larger layoffs to protect the little people and prevent discrimination. Ignoring them will spawn lawsuits as well.
