How OSP site supervisor pay ranges in Swaziland

A good way to think about salary in Swaziland is to look at the distribution rather than the headline average. Half of all OSP site supervisors in Swaziland earn less than 31,520 SZL a year, and the other half earn more. That middle number is the median, and it is usually more useful than the average for answering "is my pay normal here".

Looking at the quartiles fills in the picture. A quarter of earners take home less than 22,420 SZL (the 25th percentile), and a quarter clear 41,980 SZL (the 75th percentile). The middle 50% of OSP site supervisors sit somewhere inside that band, which is where the typical reader of this page probably lives.

The very lowest reported salaries sit around 17,760 SZL. The highest stretch to 52,380 SZL, though only a small fraction of earners ever reach that level. If you are deciding whether your own offer or current pay is reasonable, work out which of those four bands you would fall into and use that as your reference point.

OSP site supervisor pay by experience in Swaziland

Years of experience is the single biggest lever on pay for an OSP site supervisor in Swaziland, ahead of education and almost any other single factor. The longer you have been in the role, the more your employer can trust you to handle complexity, mentor others and act independently, all of which command higher pay. The chart below shows how the typical OSP site supervisor salary changes as you move through the career ladder.

  • 0-2 Years
    21,020 SZL
  • 2-5 Years
    +18% from previous
    24,720 SZL
  • 5-10 Years

    +4% from previous
    45,260 SZL
  • 20+ Years
    +11% from previous
    50,020 SZL

The single largest jump on the ladder is from 2 - 5 Years to 5 - 10 Years, where pay rises by about 46%. That is the point at which a OSP site supervisor typically goes from "competent in the role" to "the person other people in the team learn from", and the market pays well for that step.


OSP site supervisor pay by education in Swaziland

Education sits alongside experience as one of the biggest factors driving OSP site supervisor pay in Swaziland.

OSP site supervisor gender pay gap in Swaziland

The gender pay gap is a stubborn feature of almost every labour market, and Swaziland is no exception. Male OSP site supervisors in Swaziland earn an average of 38,180 SZL a year, while female OSP site supervisors earn around 31,180 SZL. That works out to a 22% 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.
