A worker won $600,000 after Twitter said his goodbye messages showed he had resigned. The case holds valuable lessons for staff and employers.

A former Twitter employee, Gary Rooney, won about $600,000 for unfair dismissal after Twitter assumed he resigned by not responding to Elon Musk's "hardcore" work email.

The case highlighted the importance of clear communication between employers and employees, especially regarding significant changes in employment terms.

Rooney’s private Slack messages, where he discussed leaving, were used as evidence by Twitter, underscoring that internal communication on platforms like Slack is not always private and can be used in legal disputes.
