Violations of the AUP — even by individual employees — can trigger account suspension or termination, making organizational oversight of user behavior important.
If you use Slack through your employer, your organization — not you — controls your workspace data, including messages and files, and can access or delete them. Slack retains rights to use aggregated and de-identified data derived from your usage to improve its services.
