Equal Opportunity Employer

• Is Equal Opportunity Employment really equal?  
• How does a firm guarantee that the hiring process is not biased? 
• How does a firm guarantee that once an employee is hired, biases will not be present in the employment process?

I once worked for a company many years ago that would openly make promotion decisions based on whether an employee had a family and was the sole breadwinner for his or her family. 

A man was more likely to be promoted because he was considered the breadwinner, and a more loyal employee because of "his responsibilities" for his family.  At the time I was young and inexperienced, and their decision-making process seemed logical to me.  The company went out of business shortly after I (a woman, and not the sole breadwinner for my family) left for a better opportunity.  Enough said. :)
