I forget which Scandinavian country this is true for but I think there exists a country where compensation is a matter of public record.
I support this 100%. I want everything to be transparent here. I know where I stand skills and competency wise compared to my colleagues so I will be ok making less than those I am less skilled or less productive as. That being said I think I’m underpaid. A transparent pay structure will only benefit the employees as we learn in Economics: the more information about prices there are in a situation the better each actor can make choices.
