Amid concern about Google’s ability to censor online content, the tech company made an attempt last week to curb some of the internal discussion and debate among its employees in order to promote a more productive work environment.

Google issued a set of “Community Guidelines” last week in an effort to restrain its employees from trolling in internal messaging, saying it would punish employees who discriminate against or attack their colleagues, or participate in conversations that are “disruptive to a productive work environment.” They also are allowing their volunteer employee moderators more power in monitoring thousands of intranet discussions, including letting them develop tools to better enforce the rules, according to The Wall Street Journal. While Google has punished employees in the past for violating its code of conduct, the guidelines represent the company’s first explicit intervention in these sorts of internal debate discussions.
