In this paper, worker and job flows are estimated using the IRP5 data from the South African Revenue Services. The data used in this paper is from the 2011-14 tax years and contains information on more than 12 million individuals and nearly 300,000 firms. The main finding of the paper is that worker flows are substantial, more than 50 per cent per year. Job flows are higher than previous estimates. The findings suggest that rigidity in the labour market does not come from rigidities in employment adjustment.
