The correct answer to this open question is the following.
I would choose the frictional unemployment, that is the result of a common turnover ratio in the work market. The reason why is because it gives employees a chance to aspire to new and better jobs. Sometimes when you stay in one place too long, you create a routine that limits new creations and squash new ideas. It is good to leave and try something new although it represents a risk and often there is a time lag to find the best job in the market. One that matches your aspirations, salary, and possibilities of growth in the company's hierarchy.
