This article sheds light on the so far under-researched effect of subjective job insecurity on social policy preferences and the moderating role of employability. Using pooled individual-level data from the European Social Survey for workers from 11 Western European countries, it shows that subjective job insecurity does increase demand for redistribution. This effect is conditional upon employability perceptions, that is, expectations about future employment prospects. The impact of job insecurity on redistribution is strongest for workers who fear long-term unemployment. The findings do not seem to be driven by underlying political belief systems as they are robust in a reduced sample of centrist non-partisan workers. While the results confirm the hypothesised repercussions of labour-market flexibility on the individual level, aggregate effects should not be exaggerated, since the segment of workers exposed to job insecurity and low employability at the same time is rather small.
