If you happen to work for a private company in Cambodia, they only bother with your employment period and step which means your salary will be raised when you stay at a company longer. They never count the never ending inflation; and you need to bear in mind that as a Least Developed Country, inflation in Cambodia will never stop. The more growth we want, the more inflation we have. It’s so natural.
However, for United Nations staff, their salaries will be raised based on Steps and Inflation. They calculate carefully the inflation rate of each year and inform their staff about the salary the following year.
