In 1987, the government of British Columbia (BC) passed the Teaching Professional Act and created the College of Teachers to certify the teacher qualification and to implement ethical codes. At the same time the government abolished the compulsory membership of the Teachers' Unions, once a non-professional force which dictated the policy of education. As a consequence, the relationship between the unions and the government has been marked by mistrusts, due to the frequent intervention of the Unions for their interests. It made a seriously negative impact on schools and learning process. To enforce the Teaching Professional Act, the government introduced a policy designating teaching as an essential public service, and consequently, the Unions cannot disrupt it. This is a case worth of learning. Furthermore, BC college of Teachers is organized so that teaching services is professionalized, professional standards are implemented. With the decrease of the role of Teacher Unions is the increase of the role of the governing council, which is empowered to makes more progressive innovations possible. As expected, the Teacher unions are regrouped in political coalitions and fight for their benefits.
