The employees may be able to latch onto another lawsuit against Twitter that alleges different severance-related violations, but their claim under ERISA was denied by US District Judge Trina Thompson in the Northern District of California. "Plaintiffs are not without recourse," Thompson wrote, noting that they may benefit from similar cases ongoing against the Musk-owned firm.
