Another worker is accusing Google of unfair labor practices after being fired for creating a browser pop-up that could be seen by the company’s employees. It read: “Googlers have the right to participate in protected concerted activities.”

Google, which is already facing charges of anti-union retaliation after it fired four employees before Thanksgiving, is now facing a similar charge brought by Kathryn Spiers, a security engineer who was fired Friday. A filing by the Communications Workers of America with the National Labor Relations Board, which was seen by this news organization, said Spiers’ job responsibilities included notifying employees of their rights to protected activity as required by previous NLRB charges against Google.
