In Minnesota local governments report job classes, whether or not the job class is female or male dominated or neutral & pay ranges for that job class. Why? To determine if there are any patterns of paying jobs dominated by women less than jobs dominated by men that are of similar work value.

P.S. Conventional wisdom would have us believe that knowing everyone's salary acts as a demotivator. I believe the opposite is true -- not knowing salaries increases the level of distrust between employee and employer and increases the likelihood of pay inequities. This is true for any internal equity issues -- not just gender.
