easingly justified. When the volume of satisfaction/productivity studies made it possible, reviews of such research began to appear, and then reviews of the reviews[14]. As a result, there is now a growing consensus that, except in isolated cases for relatively short periods, there is no generalisable, reliable, functional link between work satisfactions and productivity in industrial settings[12, 15, 16, 17, 18].Indeed, there is considerable evidence of a reverse connection — that some people are satisfied by the opportunity to work hard[19, 20,21]. Growth of the Service Sector Just as the agricultural sector declined from 90 per cent to 5 per cent of employment due to the rise of industry, so the service sector has been growing at the expense of industry. For example, in 1929 40 per cent of all jobs in the United States were in services, but this grew to over 50 percent by 1950, to 55 per cent in 1967, and by 1980 service employment was estimated to be over 80 per cent[22, 23, 24] with predictions that it will reach 95 or 97 per cent by the end of this century[25,26]. In Sweden, serviceproducing jobs grew from 45 per cent of all jobs in 1965 to 59 per cent in 1976[27]. By 1980, service employment accounted for more than 50 per cent of all jobs in Japan, Belgium, France, the United Kingdom and the Netherlands, and was larger than either industrial or agricultural employment in both West Germany and ltaly[28]. Of the new jobs created between 1973 and 1980 in the United States, 70 per cent were in the services[29]. Research in the Service Sector Despite this constant growth in the service sector, grounded knowledge concerning personnel needs, work patterns, work satisfactions, etc, in the services lags far behind. Part of the reason for this situation is that judging the effectiveness of services, and evaluating service workers, has been found to be fraught with difficulties[30], and termed the most perplexing and troublesome issue in productivity studies[31]. Importance of the Research If social workers39。 lack of job satisfactions impact negatively on the quality of the service which they offer, then the profession of social work — concerned for the wellbeing of clients — should pay a great deal more attention to improving those conditions at work which cause social workers to be dissatisfied. Simultaneously, social work education should then redouble its efforts to graduate only those students who can isolate their personal feelings from their professional roles. By extension, all of the human services may be faced with the same problem, and as the service sector continues to expand, the search for satisfying job conditions, on the one hand, and education in selfcontrol, on the other, may be prerequisites for effective services. However, if there is no relationship between social workers39。 personal feelings and the quality of the service which they offer, then improvements in work conditions to make workers more satisfied for their own sakes (that is, to improve the Quality of Work Life) as proposed by Glicken[58] may be indicated, but efforts to improve services can concentrate on other areas and subjects, such as better diagnoses, more resources, easier or more effective procedures, etc. Methodology Hypothesis Although it would have been desirable to study the effects of social workers39。 job satisfactions on the totality of the service offered, both in terms of process and final result, the very nature of social work p
