I work for an attorney in Missouri. Right now, we have 2 Discrimination cases pending. Just like lilhorseladie said, they are very, very, very, very hard to prove. You need LOTS of witnesses, and actual proof of discrimination. The statute of limitations is very short in most states, and in some states, (like MO) you will need to file a claim with the EEOC and have them give you a "Right to Sue" letter before you can proceed. One case has been going on for over 2 years and the other is only about a year and a half old. Both are VERY complicated cases. Make sure your friend gets opinions from more than one attorney. Some attorneys will take any case! Good luck!!
