A good comparison can be seen in the world of sports. When your contract expires you become a free agent. Simple concept but true. As a free agent I can stay where I am or go somewhere else. Most of us would prefer to stay with the home team and may even allow for a home team discount. For me that home team discount would be the first year of my new contract at half price and no need free new equipment. Not as good as the competing offer but because I like where I'm at I'll accept the home teams offer. Now if I'm not in demand then they will dump me in a heart beat. That's why pro sports players have representatives. Because they know it's not a matter of loyalty, it's just business. Show me the money!
