Slack DMs feel private to most workers, but they are not. On a recent All-In podcast episode, Salesforce CEO Marc Benioff said the quiet part out loud, telling listeners he uses AI to read what his staff are griping about.
Benioff told the show that Slack's AI agent now reads through every DM and channel a company runs to surface frustrations, business issues, and operational gaps in real time.
He uses Slackbot - Slack's built-in helper - to ask questions like "what are my employees upset about," then gets a live answer back in seconds. The same agent can pull up his top deals, employee concerns, and top priorities on demand, which Benioff says tells him more about his business than he already knew.
Salesforce bought Slack in 2021 for $27.7 billion, which means every workspace is now feeding the same AI system that Benioff openly queries about his own staff.
The legal cover is already settled, since Slack's privacy page states that the customer - meaning the company - owns and controls all content in a workspace. Workers don't.

This is the new workplace data loop, where worker chat becomes data and data becomes intel that drives the next round of layoffs, hires, and product bets. The firms selling those tools are sitting on a goldmine of corporate behavior they can resell or use to lock in clients.
Microsoft is running the same playbook with Copilot inside Teams, Outlook, Word, and Excel, while Google's Gemini reads through Workspace email, docs, and chat. Glean, one of Silicon Valley's hottest startups, pitches itself as a search engine for everything happening inside a company.
The trend stretches well beyond chat apps. Meta is using employee keystrokes and mouse movements to train AI agents, AT&T tracks in-office attendance, and JPMorgan watches how often its engineers use AI tools through internal dashboards.
For investors, each of those tools is one piece of a fast-growing market. Companies will pay almost anything for software that squeezes more output from the workers they already have.
Whether more CEOs follow Benioff's lead in public - or quietly back off once workers fully grasp what their employer can see. The legal cover for this is settled, but the cultural cover is not, and watch for the response to show up in new employee handbooks and union demands.
