Slack and Teams Etiquette

Chat tools like Slack and Teams have quietly become the main office. We greet colleagues, ask questions, and make decisions there all day. But speed has a cost: a careless message can interrupt ten people, and a vague one can waste an hour. Good chat etiquette is not about being formal — it is about respecting other people's attention.

Rule one: put your whole point in a single message. Many people type "Hi" and hit send, then start writing the real question while you sit and stare at "is typing…". Instead, write it all at once: "Hi Sam, can you approve the invoice for Client A by 3 p.m.? Here's the link." One message, one clear ask — the reader can act immediately.

Rule two: use threads. When a channel has thirty people, replying in the main flow buries every other conversation. A thread keeps one topic together and spares everyone else the noise. Before you post, ask: does the whole channel need this, or just the two of us? If it's just us, a thread or a direct message is kinder.

Rule three: treat @-mentions as a tap on the shoulder. "@channel" and "@here" ping everyone, so save them for things that are truly urgent for the whole group. Mentioning one person by name is fine when you need them specifically, but resist tagging five people "just in case". Every needless ping trains people to mute you.

Rule four: respect status and hours. A green dot is not a promise to reply in one minute, and "Do Not Disturb" means exactly that. If a teammate is in another time zone, schedule your message to arrive during their working hours rather than pinging them at midnight. Async by default; interrupt only when it genuinely can't wait.

Rule five: know when to leave the chat. Some things do not belong in text at all. If a thread has gone back and forth five times, or the topic is sensitive, emotional, or easy to misread, stop typing. Say, "This might be quicker on a call — free in ten minutes?" A two-minute conversation can settle what twenty messages cannot.

None of these rules are about strictness. They come down to one idea: your convenience is not more important than someone else's focus. The colleagues people trust online are the ones whose messages are clear, whose pings are rare, and who know when a real conversation beats a keyboard. Be that person, and your name becomes one people open first.
