Hi!
Looks like there is a serious compensation terminology gap that needs clarification on this site. Indeed, it's been some time since I have seen many use the term "salary structure" to refer to "salary components", and others use the term "salary scale" to refer to "salary structure".
I don't know if we are using different dictionaries and/or different HR/Compensation reference materials. I am also wondering if dictionaries have different meanings in each continent or country.
I think HR practitioners must learn to use compensation language when discussing compensation matters, so they can understand each other better. A good source for compensation terminologies are international compensation consultants like HayGroup, Hewitt Associates, Watson Wyatt, and William Mercer. By reading their regular annual compensation survey reports for each country, you will easily grasp compensation language and terminologies.
Just for clarification, the following are the appropriate definitions of the terms mentioned above:
Salary Structure - refers to the designed "total salary range" of an organization composed of Job Grades or Bands, with each Job Grade having its own "internal range" called minimum, median, and maximum rates.
Salary component - refers to the "mix of a compensation package" typically offered to an employee during hiring. In compensation lingo, an employee's salary is generally a mix of the "base salary" and "benefits". The base salary is commonly known as the "basic pay", while the sum of base salary and benefits is referred to as "Gross Pay". Therefore, those who mention that the salary consists of base pay plus cash and non-cash benefits are actually talking about "gross pay".
There is no such thing as "salary scale" in compensation terminology. It seems to be a term used only on this site by some HR practitioners. According to Webster, a scale is "a measure characterized by marks along a line, with regular spaces in between, used for measuring" (e.g., thermometer).
I hope this clarifies things.
Wishing you happiness and good health in 2010.
