Hi!
This Salary Structure is a very old model and what is usually called the "Thirty Year Employment Chart". I have also seen a similar chart in the Middle East and I called it the "One hundred Year Salary Chart".
As shown by the given example, each Job Grade has thirty (3) steps and an equal increment of Rs 200.
With that information, we can easily conclude that the company's methodology for increasing salary every year is based on seniority. As such, every year, all employees get an increment of Rs 200 regardless of their performance.
This salary structure can last the employment life of many of the original employees. Indeed, the first batch of employees would be retiring before they can reach the 30th step.
Modern Salary structures are reviewed and adjusted every three (3) to five (5) years. Their rates are also benchmarked with industry rates. Otherwise, they may not be able to fullfill the second principle in Compensation --- i.e. External Competitiveness.
Today's organizations and employees would prefer a performance based methodology. Indeed, outstanding performers in many organizations would like to be paid more than the ordinary performers and/ or non-performers.
Also, modern Salary Structures provide more leeway to management relative to the annual increases. Hence, many structures woudl simply provide the minimum, median, and maximum rates and allow the immediate managers to recommend the appropriate increases per employee --- depending on the result of their annual performance review.
Best wishes.
