Measuring sustainable development requires multidimensional attitude as the process is characterised by compound relationships between social, economic and environmental spheres. The paper aims at assessing selected effects of sectoral employment for the three dimensions of developmental processes. We examine employment efficiency in 25 EU countries concerning four sectors: agriculture, industry, market services, and non-market services. We use a non-radial DEA input-oriented model, which allows the assessment of the general efficiency of labour resources, as well as the evaluation of in-depth efficiency in the three dimensions of the economies under study. The novelty of the research lays in both multidimensional attitudes to the effects of labour engagement as well as intersectoral comparisons of the employment results. We categorise the EU countries according to efficiency in gaining the sustainable development and its three dimensions. Generally, the "old" EU members are of higher efficiency than the "new" states. Our research shows desirable movements of labour force that are necessary to improve efficiency and thus offers some advice for a rational development policy. It appears that it is necessary to limit agricultural employment in favour of non-market and market services and, to a lower extent, of industry. We conclude that the structural changes in employment specified by patterns observed in the highly developed EU countries are favourable for realising the aims of sustainable development.
