According to a recent study, most people significantly underestimate what people are earning in similar jobs elsewhere. The researchers argue this holds back people from seeking better paid jobs or higher pay for their current role, and that it particularly disadvantages the lowest earners. They suggest that if workers were more aware of salary disparities, at least 10% of low-paying jobs would simply not be viable at current pay rates.
