Doesn't matter. It is a lopsided relationship. As an employee, it is massive portion of your life. From the employer perspective you are a resource, and can be replaced (not making a moral judgement, just saying that you can...). So the fact that someone can leave after 2 years is less impactful on the company than a company that forces you to leave after X years. If on the other hand you are just saying "well it is unlikely you will get to 9 years" the problem with that thinking is that the closer you get to 9 years and the more you have invested the more likely you will want to stay for 9 and being forced out for no reason is silly. It is a job, not the presidency.
