What is Slack?
We’re glad you asked! Slack is where work happens. It’s a digital workspace that powers your organization — all the pieces and the people — so you can get things done.
The people of your Slack workspace
A Slack workspace is comprised of the following people:
👑 Workspace Owners
🤖 Workspace Admins
Here’s how it works: A Workspace Owner creates a Slack workspace, recruits Admins to help manage and organize the team, and they together invite and onboard members.

The pieces of your Slack workspace
To understand how Slack really works, it helps to know how all the pieces fit together. Here’s a snapshot of what a typical Slack workspace looks like:
And here are the main components we'll break down for you, piece-by-piece:
- teams and workspaces
Teams & workspaces
A team is a group of people that use Slack to communicate. Your team is likely comprised of the people you work with every day. Your Slack workspace is the digital space you and your teammates share to communicate and get work done.
If you’re part of a small to medium-sized company, you and your fellow co-workers will likely all be members of one Slack workspace.
If you’re part of a larger organization — possibly comprised of many locations, people, and sub-groups — you may have multiple interconnected Slack workspaces. Each workspace is independent, but all are interconnected and powered through Slack’s Enterprise Grid.
Within your Slack workspace, you’ll have access to all the other pieces that make your work hum along.
Your Slack workspace is comprised of channels. You’ll use channels to hold most of your conversations with other members. They can be organized around anything — departments, projects, or even office locations — and you can create as many as you need. Every workspace starts with two channels by default: #general and #random.
Tip: All members are required to be in #general, making it great for company-wide announcements and updates.
In Slack, there are three kinds of channels:
👀 Public Channels
They're open to your entire team. All messages within a public channel are archived in Slack and are searchable by all members, except for Guests of your workspace. You can identify a public channel by the # hashtag icon next to its name.
🙈 Private Channels
They're not open to your entire workspace. You have to be invited to join a private channel to view and participate in the channel's discussion. All private channels have a lock icon next to the channel name.
🔗 Shared Channels (beta)
They're a bridge connecting a channel in your workspace with another company’s Slack workspace. Shared channels, public or private, are a great place to communicate with external contacts. A shared channel has a double diamond icon next to its name. Read more about Slack's shared channel (beta).
Here is an example of a discussion taking place in the private channel, annual-meeting. These teammates are preparing for their department’s annual meeting in a channel that only they can access — notes, messages, and files included.

When you need to quickly chat or check in with teammates, you can send them a direct message (DM). Direct messages are best for ad-hoc, quick discussions. These conversations are only visible to and searchable by you and the other members you DM. You can DM just one person, or start a group message with up to 8 other people.
💡 Read more about direct messages and group DMs.
Communication in Slack happens through messages, whether they’re in channels or DMs. Most communication should happen in public channels to create a transparent and searchable archive of your team’s work. No matter where they’re shared, you can format your messages to help present your ideas. Did we mention emoji? Use them to enhance your own or to react to your teammates’ messages.
Tip: If you need to call the attention of someone specific, type @ followed by their display name to send them a notification. We call this an @-mention.
Here’s a message someone’s working on for the upcoming team meeting:
With the transparent flow of information in Slack, Search is your way to narrow down and find the information you need to get work done. You’ll notice a search box in the upper-right corner of Slack — it’s there any time you need it. Simply type a word or phrase in the search box to start looking. You can even use a number of modifiers to help you narrow your results.
Notifications are Slack’s way of telling you about items that need your attention. You can choose to receive notifications on your desktop, your mobile device, or by email. Notifications can even be customized by channel, so you can prioritize where your attention goes.
