The Communications Workers of America (CWA) union has filed a complaint against Activision Blizzard with the National Labor Relations Board (NLRB).

The filing – as reported by Polygon – names the company's new chief communications officer and EVP for corporate affairs, Lulu Cheng Meservey, who is alleged to have posted "anti-union propaganda" in an internal Slack channel. This was later shared on Twitter by the CWA's Jessica Gonzalez. Said Slack channel was the #ABK-press room, which is viewable by around 18,000 workers. 

The CWA claims that Meservey "coerced and restrained employees" who were looking to exercise their right to join a union by "admonishing all staff not to share anything other than 'discreet and respectful' communication" about Activision's position on unions.

Meservey's alleged message shows the communications chief complaining that union bargaining is slow and adds that Activision Blizzard would rather have a "direct dialogue" with its employees. The Washington Post's Shannon Liao reports that staff were unable to reply to this message, instead choosing to post negative emojis to register their feelings. Meservey later responded to her initial message, saying "I can hear the booing from here! And have registered the disappointing dog emojis."

All of this comes in the wake of news that the NLRB had given the nod to QA workers at Blizzard Albany to have an unionisation vote. Meservey joined the company earlier this month.
