The badging system will notice someone has not left. This should have made security panic a fair bit on Friday evening...

They might have a lot of tailgating in and out, which makes badge info unreliable.

Would they notice that she had not badged in or logged in on Monday morning? Unless she had already taken time off starting Monday.

They probably aren’t monitoring badge data at all in real time, most offices don’t.
