The advantage of the position of Senior Officer is certain responsibilities are stressed by time. In that case, it will better fit school environment.

No problem.

The reason is quite simple - the name "Education Officer" is misleading. In fact, your work is a senior administrative assistive.

However, the position of Senior Officer is a supervisory position, as well as a senior administrative assistive.

You will benefit more from the position of Senior Officer than the Education Officer.

月薪萬九與月薪萬六，只是在一堆爛蘋果裡面挑選。筆者，不是箇中高手。
為什麼不選擇萬九加上萬六的工作？
坦白說，港幣三萬五的月薪，此時此地，亦只是雞肋而矣。
