This seems like it completely misses the point of Slack: if someone is harassing you, you don’t report it to Slack Inc: you report it to your company’s HR department. And when your harasser tries to sue for wrongful dismissal, the company’s legal department has access to their DMs to present in court.

A product that has these features is the wrong tool for a large company; and similarly, if you need these features then Slack is the wrong tool for that job. Changing that is a social problem that would require restructuring the way we think about workplaces, not a technical problem that can be solved by getting Slack to add a few features.

Many (maybe most?) Slacks are not run by large companies. Seems reasonable for there to be a "work like Element" toggle for those use cases.

I'm all for end to end encryption but the fact is most employers need access and have a right to access these chats.

Why? I don’t think managers use Slack if they know that these messages are readable by everyone.

It certainly makes it easier to comply with discovery orders in those legal cases large employers seem to get involved with much of the time.

Anyone with Slack admin rights knows its possible to access the chats currently, same with Teams.

They wouldn't use it for gossip but its acceptable to discuss reportee matters if they know only their seniors can access the chat and its all above board.

Otherwise take it offline and talk in a meeting room instead.

Slack is a product owned by a company. If you don't like it, don't use it. Trying to get Salesforce to implement a change to their product via activism is laughable.
