Labor turnover is expensive – and even in these times of elevated unemployment, manufacturers try to minimize it.
Interestingly, there appears to be a correlation between turnover and the presence of labor unions – though it may not be what you expect. Among non-U.S. facilities, turnover tends to be higher where there is significant union presence.
Average turnover in this international set is 27% where more than a quarter of the workforce is union – compared to 17% where less than a quarter of the workforce is union. As turnover rates decline (toward zero in the 90th percentile), so too does the difference between union and non-union shops.
The story is different for U.S. plants, where the correlation between unions and turnover all but disappears. But if anything, the data lean slightly toward lower turnover in facilities with significant union representation. The average turnover is 10% for shops with more than a quarter of workers in unions; it’s 12% where fewer than a quarter of workers are in unions.
