Has this ever happened? I know that in the US at least we say that "you can sue anyone for anything," but it seems a stretch to think that a company could face legal liability for disclosing internally that someone was let go.
exactly -if I ran a big company, no way I would send out a notice to people still working there every time someone was let go to say who got fired or laid off.
People who need to know find out who is gone, it just takes a little longer.
Step 2. The list is shared on social media.
Step 3. A former employee that's on that list sues the company.
