Largest union federation in the US demands apology from Mark Zuckerberg over new software feature that would allow employers blacklist words like 'unionize' in chats

Facebook's Workplace functions as an internal message board for corporate clients, an answer to Slack or Microsoft Teams. This week, The Intercept reported that Facebook was promising those clients the ability to exert "content control" over their respective news feeds. Specifically, it said companies could suppress the word "unionize."
