The supernumerary contract workers recruited by the Education Bureau are guaranteed. As long as you sign the employment contract, you can enjoy five insurances and one gold. The salary is the same as that of a series of teachers, but the salary is lower. Most of the salary is distributed by the region or school. Many times, you can't raise your salary without taking part in the professional title evaluation. Generally, the contract signing time varies from several years, and the probation period is generally three months. When you become a full member, you need to pass the exam. If the examination fails, the employment contract shall be terminated. When the contract expires, the school will not renew it with you. Then you are not a teacher in this school, which means you are fired.
