Pay commission

The last caretaker government formed a pay commission. Recently, they submitted their report to the government. In this report they fixed Tk 4,000 as the lowest amount of basic pay instead of Tk 2,400. The highest salary will be Tk 42,000. The increase for the lowest scale is 66.67% , but, on the other hand, for the highest scale it is 82.1 percent. Why this discrimination?
