Elon Musk's face on a computer screen with the logo of Twitter reflected on it.
Elon Musk took over Twitter on October 27.
  • Elon Musk last month offered thousands of laid-off Twitter workers a limited severance deal.
  • Over 1,000 of the workers are now fighting for more through arbitration, a costly legal process.
  • With many claims and more expected, Musk faces tens of millions of dollars in legal costs and fees.

Elon Musk has repeatedly said Twitter is teetering on the brink of financial ruin. Yet the cost of legal battles with well over 1,000 laid-off employees, who say they were promised better severance terms, could be enough to push it over the edge.
