You've just been fired, or the job or promotion you know you earned has just been given to someone with half your qualifications. Suspiciously, that person may also be much younger, white, and male. Do you have a case? It depends. The temptation might be to jump to the conclusion that you are a victim of discrimination. And you may be. But the question you need to focus on is whether you were discriminated against in a way prohibited under the law, which is a rather different question from what common sense may tell you. No matter how outrageous an employer's decision, the law will not allow you proceed with a discrimination claim unless you can meet the law's extensive, technical requirements.
