Some of the blocked terms included “union,” “slave labor,” “grievance,” “living wage,” “prison,” and “plantation.” Even using the word “restrooms” was disallowed, likely due to claims that many employees, especially delivery drivers, are forced to urinate in bottles because of the unrealistic targets and deadlines imposed on them.

A list of words was devised that would be blocked if they appeared in any employee messages—the app was to be more like dating app Bumble, where workers engaged with each other one on one, rather than something more traditional like Facebook.
