In recent years, the use of temporary employment has increased in most industrialised countries, which has stimulated research about their consequences for employees and organisations. Since temporary employment by nature is an insecure employment form it is often assumed to be associated with impaired well-being and less preferable work attitudes. However, findings of previous research have been inconclusive. Some studies report no clear differences to permanent employment; some find support for the assumed detrimental effects of temporary work, while yet other studies report positive effects on employee well-being, attitudes and behaviour. It has often been argued that the role of individual motives for working in a temporary assignment, the voluntary choice of the employment contract as well as the level of work involvement might be crucial in explaining these mixed results, but few empirical studies have so far been carried out to examine this hypothesis. In this paper, we therefore aimed to clarify how different patterns of motives, volition and work involvement among temporary employees are related to their self reported attitudes and individual well-being. The study uses questionnaire data gathered during 2004 from temporary employees (N = 183) in three different employment sectors (education, food industry and sale) in Sweden. Performing a cluster analysis, six distinct subgroups of temporary employees have been identified, each of them showing a unique pattern of motives, volition and work involvement. Current analyses of variance that are being carried out compare these subgroups in terms of their work attitudes and their self reported well-being as defined by a number of work-related indicators (e.g. work-home interference; job satisfaction), as well as some more general measures (e.g., general health, irritation). Thus, this study adds to the existing knowledge about the consequences of temporary employment in several ways. Whereas motives of temporary workers have been described earlier, there are only a few studies that have related them to outcomes in terms of attitudes and well-being. The role of work involvement of temporary workers has seldom been addressed and the effects of volition have so far only been studied in variable-oriented approaches. Choosing a pattern approach carries the advantage of a holistic perspective taking into account a pattern of variables as the main analytic unit. As a result, this paper will demonstrate what insights can be gained when patterns of temporary workers’ motives, voluntary contract choices and work involvement are analysed in relation to well-being and work attitudes.
