The circular states that the total allowances payable to employees of each given parastatal should not exceed 30% of the organization's salary bill. This means allowances like housing, transport, clothing etc when added together should not surpass 30% of the total amount an organization spends on salaries each month. This 30% cap is meant to limit allowances and control salary expenditures by public sector organizations. So in summary, it is not an additional 30% payment, but rather a limit on total allowances equal to 30% of the monthly salary bill.
