Occupations vary in how much they pay, but they also vary in the rate of which their pay changes. The disrupting force of technology, as well as government pay restrictions during austerity, mean some occupations are paying their workforce less than a year ago.
I plot government data below from 2015 on the percentage change in earnings over the previous year.
The data below suggests that the worst-performing group was air travel assistants, publicans and sheet metal workers. Surprisingly, higher skilled occupations are also on the losing list, including Vets. In contrast, some of the occupations with the highest increases were cooks and those working with glass.
