So you are free to record work meetings and post them on TikTok?

Legally, yes.

But she could experience some consequences if future employers don't feel great about this.

What about NDAs?

What hashtag should I follow to watch more US corp internal meetings?

How did she break an NDA with this video?

You are right you cant just record and out out there just ANY corporate material. But you getting fired? This aint it.

Making them? Sure. Sharing them on chinese owned social network? I'd be very very surprised.

If it's a legally-made recording -- and thus the property of that person who pressed the "record" button, free and clear of any obligations -- what could be illegal about posting it publicly?

As others have already mentioned, she could have signed an NDA, but those are typically narrow and only apply to technical data, marketing data, sales data, etc. There could be something in there about "internal processes," but it's a stretch.

She could have signed a non-disparagement agreement, but there's nothing in the video which constitutes disparagement.

So I'd assume that she's probably okay. And she did a good thing by posting it.

Besides, legal action would need to come from Cloudflare, which would be an extremely bad look for them.
