I can still remember the moment when I realized two male peers were making 20% more than I was despite our roles, responsibilities and time in our jobs being almost identical. The company had just handed out our expected United Way contributions and the HR director made the mistake of saying the number on our forms was based on 5% of our annual salaries. Since my male peers were sitting beside me, it was not hard to see that my contribution was lower than theirs. I quickly did the math in my head. Now what? Sure, I had suspected they might be making more but now I knew.
