The first is that your boss may be able to see your direct messages if you have the paid version. It is important to check if the setting is enabled in order to keep your DMs hidden. There’s a simple way to do this.

Slack gives workspace administrators (i.e. the person managing your company’s Slack account) the ability to determine how long messages — both in public channels and direct messages — are saved. It could be 90 days or forever, for example. However, workspace owners can give their users the option to change the retention settings of conversations in which they are involved.

If you have this power, you can and should adjust this setting on your own direct messages. Imagine this: If your boss wanted to see all of your direct messages, it would be better if he had a record of them for years. Or only the last 24 hours? Yeah, exactly.

Click on the gear icon at the top-right corner of the conversation and then select “edit the message retention.” Next, click “Use Custom Retention Settings for This Conversation,” select one day (the shortest time period you can choose), and then click save.
