If I make more than they do and they think they should make the same amount, what’s to stop them from storming into the HR department and bringing my name up as a reason that they should make more?
Even though it is illegal to fire someone for discussing salary, that and a nickel will buy me a piece of five cent candy.
If they make more than I do, what am I going to do with that piece of information? I can’t very well bring it up at salary negotiations.
Besides, I have been around long enough to know that the best way to “get a raise” is to change companies.
