She did an extremely stupid thing - deleted a wrong person from a database. She wanted to delete someone who was fired on the same day they came, so they didn't need a record at all. But she misread their last name and deleted someone who already have records. More than that, she did it 10 days ago.
Now I'll have to restore it manually and into the closed month too. If she will repeat it for a third time, I.... i don't know what would I do, but it wouldn't be pretty. Or legal.
