Re: She did it to herself
I will point out that a lot of companies have wage secrecy in their contracts. Illegally, of course, but even the HR people don't seem to realize that till you pull out the relevant law - the name of which escapes me at the moment - and show it to them. That being the case, it's entirely possible she didn't know and found out by accident. My ex-wife ran into a similar situation. She was the only woman on her team and after being there for a year found out that not only was everyone else making minimum 75 cents an hour more than her but that there were guys hired after her at a higher wage. When she brought it up to the HR person there she was first told that discussing salaries was a breach of policy. But to their credit they also gave her a retroactive pay raise back to the day she was hired. Her paycheck that week was impressive.
