HR business in any org is to ensure people/dept/ BU contributes to profits (which is right hire & right fire). I know lot of companie who do lot of dance & song for their employees and consider that this is whatHR is.. but certainly those HR people IQ & substance is very much visible from their focus & approch.
Each function in any org has clear objectives like Sales, finance, Ops & HR each leads to profits or create condusive envorinment for profits. if at any fails org profit leakage starts.
So in all str'gy & skill to contribute to org profits could vary from function to function but goal reamins same. Therfore HR is all about profits its approch could be throgh people, compliance, T&D but it all ends with profits.
