One of Twitter's lawyers literally stated in a company-wide communication this morning that Twitter employees have the right to work from home, regardless of what Elon said in his email.
Elon announced the policy with the intent to be able to fire employees who refused to come in to the office. However, because WFH is part of employee contracts, enforcing a WFO policy would constitute a constructive dismissal if actually enforced by Twitter. Meaning, not for cause, severance likely required under WARN Act, etc.
Then why did Twitter's top lawyers just quit? You're being optimistic in expecting Twitter's legal team were even told about this plan in advance, considering HR wasn't.
