Question

Hello, I worked for a company in New York for 14 years and have never been promoted. I have had excellent reviews every year by over 7 different supervisors. Every time I have asked about ways to advance in the company, etc I've been told we will look into it or get back to you. I am an African American male, college educated, and no matter what I do I was not given an equal opportunity for advancement. People who were less qualified with less education were given opportunities (which I knew I could do) constantly. Finally being frustrated I put my resignation in the company gave them 3 weeks and right before my last week that company told me they would like to keep me for 10 more years and would like to discuss future career opportunties. When i asked what these were they were very vague. I saw this as the same old excuses from the past. I wanted to know if this would be seen as a case of workplace discrimination and should i file a complaint with the EEOC or is this unfairness
