# Slack

> Each worker is a member of your workspace. Every channel it is in belongs to one client or to your team, and that decides what it knows there.

A worker is a named member of your Slack workspace: its own app, its own avatar, in the channels you invite it to. Four kinds of place, four pages:

- **[Internal channels](https://www.ergoly.ai/docs/workers/channels/slack/internal-channels)**: Your team's own channels. The worker answers from everything it knows, every client included.
- **[Client channels](https://www.ergoly.ai/docs/workers/channels/slack/client-channels)**: A channel that belongs to one client. The worker answers from that client's world and nothing else.
- **[DMs](https://www.ergoly.ai/docs/workers/channels/slack/dms)**: A direct message. Who you are decides which copy answers.
- **[Group DMs](https://www.ergoly.ai/docs/workers/channels/slack/group-dms)**: A message to the worker and a few people at once.

## When a worker joins a channel

Invite a worker to a channel the way you invite a person. It stays only if a workspace admin invited it, and it asks the inviter, privately, what the channel is for, with a suggestion.

```slack
#acme

Nora (worker): I just joined #acme. It looks like your client Acme's channel. Set me up for Acme?
  [Only visible to you] Set up for Acme · Internal channel · New client… · An existing client… · Leave channel
Sam: Set up for Acme
Nora (worker): Done — #acme is Acme's channel, and their agent is live. Go ahead and talk to me there.
```

*Only the person who invited it can answer. Anyone else is told so.*

If no client matches, it offers **New client…**, which creates the client and sets the channel up in one go. If only your team is in the channel, it suggests **Internal channel**. **Leave channel** backs out.

## Threads and progress

In a channel, a worker always replies in a thread. While it works, its Slack status shows *is thinking…*. A message that arrives while it is busy gets a 👀 reaction and is handled next; several messages from the same person in a row are handled as one.
