How top research and development executive pay ranges in Tonga

Top research and development executive gender pay gap in Tonga
The gender pay gap is a stubborn feature of almost every labour market, and Tonga is no exception. Male top research and development executives in Tonga earn an average of 46,160 TOP a year, while female top research and development executives earn around 40,140 TOP. That works out to a 15% gap in favour of men, even when comparing people doing the same work.
A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.
