Grassroots worker co-operatives are a particularly appropriate organization within which to explore some major components of the construct of person-organization fit because they are explicitly constructed to fill personal needs from work. The main focus of this dissertation was first to describe the experience of co-operative members in terms of satisfaction and motivation in various aspects of work, the level of perceived value congruency between members and their organization, and reported intention to remain with the organization, and then to examine the interrelationships between these and other measures of work experience. Personality measures were included to explore the notion that some personal traits may be related to success within the co-operative environment.Members of three grassroots worker co-operatives were invited to complete a questionnaire designed to measure the variables described above. Fifty-seven members responded. Analyses of the results consisted of distributions of responses and correlations to explore relationships between measured variables.In comparisons between the personality characteristics of co-operative members and of the normative samples provided with the personality profiling instrument, a number of differences were found, particularly for the women of the co-operatives. For women person-organization fit appeared to be a unitary experience: general work satisfaction, intention to leave and value congruence were strongly interrelated, and were found to tie in with the womens interest in, and satisfaction with, the democratic decision-making process and the worker co-operative structure. The results suggest that person-organization fit is a key component of the overall quality of these womens experiences in these workplaces.For men few relationships between variables reached significance but the limited results suggest that it is the fit between personal goals and those of the co-operative as a whole which is most likely to be associated with the overall satisfaction.The findings suggest that the notion of person-organization fit may be useful in worker co-operatives. The relevance of the findings to these worker co-operatives and for future research are discussed.
