The teacher is custodian and architect of a nation. The future of our country is in the hands of a teacher. He plays an important role in upholding the cultural traditions, ideals and values of our society. The whole system of education depends upon the quality, competency, devotion and character of the teachers. They are the pillars of society responsible for educating young people of different walks of life. The statement that no system of education can raise the level of its teachers, that no programme of educational reforms can be implemented without the willing and active co-operation of teachers holds true. Teacher should have a sense of job involvement. Job involvement is a significant job related behaviour. It shows the degree to which an individual is personally involved with his job. If the teachers are highly involved towards their job, they can produce good results in their professional life.
