The split shifts do last a long time. Some longer than others. I was on them for seven months. Again, it is NOT EASY. It is a job. It is not a vacation.

As a former teacher in the West,I can return to my homeland anytime to teach there again if I wish to immerse myself once again in the kind of drudgery that you describe above.
For those readers like me who wish to get a life,try teaching in China.Avoid South Korea,especially the private sector!Nothing I have read on this board re teaching in South Korea leads me to believe that teaching there is better than doing so here in China.
