The HR world is abuzz with talk of big data and the transformative potential of HR analytics. This article takes issue with optimistic accounts, which hail HR analytics as a 'must have' capability that will ensure HR's future as a strategic management function while transforming organisational performance for the better. It argues that unless the HR profession wises up to both the potential and drawbacks of this emerging field and engages operationally and strategically to develop better methods and approaches, it is unlikely that existing practices of HR analytics will deliver transformational change. Indeed, it is possible that current trends will seal the exclusion of HR from strategic, board-level influence while doing little to benefit organisations and actively damaging the interests of employees.

However, over-employment is more likely for those who work the longest hours. The duration of the SWB penalty associated with over-employment and under-employment is typically short, but SWB levels tend to remain depressed for those who remain overemployed for two years or more. Results suggest that state and organisational policies that reduce the incidence of long hours working may enhance aggregate well-being levels.

Research highlightsWithin-person analysis of the working time-smoking relationship.Analysis based on two nationally representative panel surveys.Longer working hours associated with reduced odds of quitting smoking.Former smokers who work long hours more likely to relapse.Increases in hours also associated with increased cigarette consumption. AbstractCigarette smoking is a risk factor in a range of serious diseases, including cardiovascular disease, cancer, stroke and type II diabetes. Theory suggests that working long hours will increase smoking propensities among workers. Consequently there is a significant body of evidence on the relationship between working time and smoking. Results, however, are inconsistent and therefore inconclusive. This paper provides new evidence on how working time affects smoking behaviour using nationally representative panel data from Australia (from 2002 to 2011) and the United Kingdom (from 1992 to 2011). We exploit the panel design of the surveys to look at within-person changes in smoking behaviour over time as working time changes. In contrast to most previous studies, this means we control for time invariant aspects of personality and genetic inheritance that may affect both smoking propensities and choice of working hours. We find that working long hours tends to increase the chances that former smokers will relapse, reduce the chances that smokers will quit and increase cigarette consumption among regular smokers, and that these effects tend to become more pronounced for workers who usually work very long hours (50 or more hours a week) compared to those who work moderately long hours (40-49 hours a week).

This article develops and tests the theory that union activism is related to economic conditions using a nationally representative panel of workers from the UK. Results suggest that a fall in real wages of two percentage points and a three percentage point increase in the unemployment rate are both associated with a one tenth increase in the probability that a 'benchmark' worker will become a union activist (albeit from a low base). This relationship is largely explained by the behaviour of workers in highly unionised sectors.
