Calculation of the base salary compression ratio, defined as the ratio between the highest base salary and the lowest base salary in the government’s civil service salary scale (e.g. the base salary of a secretary general or equivalent position and the base salary of a junior expert or equivalent position). Low base salary compression ratios suggest that employees in the higher categories are underpaid or lower levels are overpaid. Differences among classes in each category must also be analysed. As a rule, the differences between higher classes should be higher than those among lower classes. The analysis only relates to civil servants. Data relates to the central government administration only. Point allocation: • 2 points = the ratio falls between 1:2 and 1:10 • 0 points = the ratio is higher than 1:2 or lower than 1:10
