A Google security engineer was fired for updating an internal Chrome browser extension to notify co-workers of their right to organize, which the company claims was a serious security violation. The engineer, Kathryn Spiers, had followed the standard approval process for changes to the extension. The firing has sparked a labor complaint and adds to recent scrutiny of Google's handling of unionization efforts. Spiers claims she was acting in the interest of her co-workers and notifying them of their rights under labor law.
