Job satisfaction?

Let’s imaging that we find the best teacher there is in the world. The absolute best and we put him/her to teach grade 1 in primary school, while he/she loves to teach grade 12 in high school… What would the outcome be? Would he/she last? Would he/she do a respectable job at teaching? Would he/she be happy teaching grade 1?

How is it they close their mind to other jobs, other opportunities? How good quality of a job can they do if they dislike it so much? How can they get a pay increase or a promotion when they clearly prefer to be somewhere else? I wonder…
