There are three argument in the article. First, to empower teachers is an ideal of teaching profession. Second, teacher empowerment will conflict with the bureaucratic system of educational administration. Third, teachers have more power or less is a dialetic process, depending on the negotiation and compromise between teachers' union and government. Teachers' working conditions in Taiwan and some countries has been studied in above three arguments the conclusions are: 1. In most countries, the entitlement of teaching profession seems inappropriate to describe teachers' work. Teachers do not have much autonomy as other professionals. 2. Teachers' autonomy in nature is imcompitable with educational bureautratic system. Thus to empower teachers but not improve the system of school management is destined fruitless. 3. Centralized educational systems will have more restriction on teacher's autonomy than decentralized educational systems do, thus to comparing teachers' autonomy in different countries is meaningless. Teachers' power should be understood in variables such as centralization/decentralization of educational organization, system of school management and socio-political change. 4. Taiwan is engaging educational reform, the 'derrgulation' has been requested. We expect teachers' power will increase in the near future.
