With hundreds of employees chatting every day, Zapier's Slack is a busy place. To keep things under some semblance of control, the People Ops team created a guide to Slack etiquette at Zapier, which is based on their original guide but made more "rest-of-the-world friendly." The guide emphasizes that Slack should be used for work-related and just-for-fun office chatter, with most conversations happening in public channels. It also advises users to default to transparency, work in public channels as much as possible, and keep posts concise and relevant. Users are encouraged to fill out their profiles, which helps the team learn about each other, and to keep their status updated. The guide also covers channel naming conventions, creating new channels, paying attention to a channel's purpose, using threads, mentioning people, and searching for answers in Slack. Additionally, it provides tips on formatting messages, handling face-to-face interactions, customizing the Slack theme, and using emoji and special reactions.
