In May 1979 the Conservative Party led by Mrs. M. Thatcher took the helm of British government. After that date the Conservatives introduced several policies, i. e. prevention of inflation, cutting public expenditure, reduction of income tax and improvement in relationships between capital and labour. In particular Prime Minister Thatcher promoted so called cheap government policy which included financial cuts in education, housing, welfare and so on. But, several social problems arose as a result of economic depression, high ratio of unemployment and riots brought about by these monetarist policies. Therefore, the Conservatives changed their social policy somehow and corresponded deliberately to each social problem. However, this does not mean the basic conversion from passive social policy to a positive one, but means a minor change which maintains the policy stance of traditional free market economy of the Conservatives. Moreover, because present political power will be judged from the nation by the general election of 1984, this kind of conversion on social policy can be grasped as political strategy. In these social, economic and political circumstances social workers in field settings must deal with more clients than before the cheap government policy. Their caseload has increased in general rather than before, and their frustrations have increased. When the Barclay Committee Report was published in May 1982, many debates resulted from these situations. The Barclay Committee Report which consisted of a Majority Report and two Minority Reports suggested a split of opinion between members. The Majority Report showed new ideas of community social work. The Hadley Minority Report showed a case of neighbourhood-based social work. The Pinker Minority Report asserted to maintain the present social work system and to continue client-centered casework. The publication of the Barclay Committee Report stimulated arguments on the role and tasks of the social worker in social administrators and social workers. Nevertheless, British social policy and social work will face a turning point in several years.
