This paper examines the determinants of job satisfaction in Britain using nationally representative linked employer-employee data (WERS2004) and alternative econometric techniques. It uses eight facets of job satisfaction for the purpose. As well as underscoring the importance of accounting for unobserved workplace heterogeneity, the paper is able to highlight some new findings that relate to differential effects of dependent children and other dependents, type of employment contract and gaps between employees' skill and skills requirements of their job. Working long hours is found to be positively associated with intrinsic aspect of jobs. Public sector employment is positively associated with all facets of job satisfaction except satisfaction with pay.
