How to Leave a Slack Workspace (2026 Guide)

There is no single “Leave workspace” button in Slack. To leave a workspace, you deactivate your account on that specific workspace, which removes you from it and all its channels while leaving your other workspaces untouched. Here is how to do it on desktop, web, and mobile, plus the difference between leaving a channel and leaving the whole workspace.


1. Leaving a Channel vs Leaving a Workspace

These are very different actions, so make sure you pick the right one.

  • Leaving a channel removes you from one room only. You stay a member of the workspace and can rejoin the channel anytime. To do it, open the channel, click its name at the top, scroll down, and click Leave channel.
  • Leaving a workspace removes you from the entire team: every channel, DM, and file in it. This is the deactivation process below.

If you are just tired of one noisy channel, leave (or mute) the channel instead of the whole workspace.


2. Leave a Workspace on Desktop or Web

Slack treats “leaving a workspace” as deactivating your account on that workspace.

  1. Make sure you are in the workspace you want to leave (check the icon highlighted in the far-left rail).
  2. Click your profile picture in the top-right corner.
  3. Choose Profile, then click the three-dot (More) menu.
  4. Select Account settings. This opens your account page in a browser.
  5. Scroll to the bottom to Deactivate account.
  6. Click Deactivate my account, enter your password if asked, and confirm.

You are immediately removed from that workspace. Any other workspaces you belong to stay exactly as they were, because each one has its own separate account.


3. Leave a Workspace on Mobile

The steps mirror desktop, routed through the browser at the end:

  1. Open the Slack app and switch to the target workspace.
  2. Tap the You tab (bottom-right).
  3. Tap the three-dot / More menu, then Account settings (or View profile > Edit depending on your app version).
  4. You will be taken to the account settings page; scroll to Deactivate account and confirm.

If you only want the workspace off your phone but not gone entirely, you can instead sign out of it: You > three-dot menu > Sign out. That keeps your membership; it just removes the workspace from this device.


4. What Happens After You Leave

  • You lose access to all channels, DMs, and files in that workspace.
  • Your past messages stay in the workspace history (deactivating does not delete what you already posted; an admin can remove content separately).
  • Your profile shows as deactivated to remaining members.
  • If you were the only owner, Slack will not let you deactivate until you transfer ownership to someone else first.

Deactivating one workspace has no effect on your account in any other workspace.


5. How to Rejoin a Workspace Later

Leaving is not always permanent.

  • Invite-based workspaces: Ask a workspace admin to send you a new invite or to reactivate your account. Reactivation restores your old profile and message history.
  • Open / email-domain workspaces: If the team allows anyone with a company email to join, you can simply sign up again at slack.com/signin with that email.

Because your message history remains, a reactivated account often picks up right where you left off.

See what people say

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.

Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.

On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
