He started out by asking Musk if he was fired. An employee has a right to know this, whether they're laid off or fired for cause. HR could have told him that, and he did ask them first, for days. Musk could have directed HR to finish his paperwork, or his manager to tell him what's up. Even if this guy was doing zero work, it doesn't matter. The employer at some point has to say your employment has ended as of today. This is generally required to be given it written form. Locking you out of systems != firing, it can be something done by accident or for a multitude of legitimate reasons. If you just want to talk about facts, it's this: as an employer, Twitter was required to give notice, and they didn't. If his written notice was as of yesterday then I think Twitter owes him for that 9 days plus whatever else his contract says.
