In Slack, work is organized into dedicated spaces called channels. Channels bring order and clarity, and you can create them for any project or team. With the right people, tools, and information in one place, teams can make decisions, share ideas, and get work done.
Public channels promote transparency and inclusivity. Members (but not guests) in your workspace can find, view, and join public channels, giving everyone access to the same shared information. Any messages or files posted in public channels will show up in search results for other members of your workspace.
Private channels are for conversations that should not be open to all members. People must be added to private channels by someone who’s already a member of the channel. Messages or files posted in private channels will only show up in search results for people in the channel.
Note: When you create a channel, you'll decide if it should be public or private. If you want to change this later, you can convert the channel.
The general channel
Every Slack workspace has a general channel, which is the only channel that members (but not guests) are automatically added to and unable to leave. This channel works best when it’s used for sharing workspace-wide announcements, and cannot be archived, deleted, or converted to private.
Channel tips and best practices
Use public channels whenever possible to ensure access to shared knowledge across your Slack workspace.
If you're on a paid plan, you can choose a template to automatically set your channel up for a specific purpose (like managing a project, handling approvals, and more).
