If both person who direct message each other do not rat, do the company they work at (who pay slack) can access direct message?
Do Slack rat their user to their client ?
Nothing is private on a device you don’t own.
Rat their user to their client
Assuming you actually mean “Can the client review messages sent on the platform they pay for, so their employees can use it”, yes, they can. Same for MS Teams.
Why do you think that is “ratting”?
If you are concerned about what you are messaging a colleague, it probably shouldn’t be messaged on your employer’s chat platform.
Nothing you do at work, on their network and software, is private
HR showed me screenshots of a private chat during a harassment suit, so no, it is not private.
You should assume that they’re not private since E2EE is not an advertised feature.
Even if it was, employers have all kinds of software running on employee workstations, some including keyloggers and screenshots, etc
Yes, slack makes private messages available to admins, though it can vary by country laws
Depends, for companies on a Pro plan or below they have to request it and slack will only approve said request if required to by law or other legal requirement (or consent of user in question)
Above that plan, only Workspace Owner admins specifically can access it. A workspace owner is the one who originally signed up for the plan and users directly designated to be a Workspace Owner from the original one.
Frankly, if it’s something that can get you in trouble DON’T use a work thing for it whatsoever! Be it slack, your work computer or work email.
If you want to talk about such things with a coworker, ask for their damn phone number or find them on SM, seriously, keep it off work stuff. There’s always a way to access even supposedly private stuff if done on a work device or service.
