You terminate one of your employees at the company. To get even, they get publicly available information about you and post it on Facebook. This causes you untold issues with identify theft etc.

1. Is this illegal? Unethical? Why?
2. What if they posted some pictures from a company party which are very personally embarrassing to you that they took which had never been posted anywhere before. In fact, you never knew they existed.
3. What if instead of working for a trip company, you worked for the federal government?
