Problem: Amy has decided to join a Startup Co. after many successful years working as a Vice-President for XYZ Inc., a large company. She posts on a professional social media site her intentions to leave XYZ next week and states: "I've greatly enjoyed working with all the great people at XYZ over the years. I'm excited to join Startup Co. though since they are greatly expanding the market in new directions. Please don't hesitate to contact me to learn more." Has Amy potentially violated any duties towards XYZ Inc.? Explain.
