Well.....I used to share my salary information until one day someone said to me that they were expecting more money from me because I make that certain amount. What people forget is that the yearly salary is the gross number. Then you have to subtract the taxes, 401K, FSA, Insurance, Stocks etc. and by the time you get the net amount, it is WAY less than the gross amount that everybody sees and remembers.
I still share the information with immediate family and just one or 2 close friends that share their information with me.
only people who know my salary are my wife, and my parents.
even my brothers know ballpark of where I am.
oh yeah and aside from them, my mortgage company, HR folks, boss, his boss..u know the drill
