Ok, with the strategy of employers to be reluctant with publishing salary info, how do you currently determine your market rate?
And given the fact that this market rate is not a clearly defined value (also thanks to employers' reluctance), don't you think it is necessary to at least negotiate with your current employer if you believe you're being paid below par?
The last time this happened to me (in 2011) I was with one of the big consulting firms and the guy in charge of recruiting put up notices everywhere with a job listing for my current position except with a 5-10% higher salary.
That being said, if I wasn't privy to this information it wouldn't take much to find out what the other people on my team are making. I don't think I've ever worked in an environment where salaries were considered top secret information.
