Employment law issues are usually very fact specific, so an employment lawyer would need much more information to be able to give you a careful evaluation. Age discrimination cases can be difficult to prove. If you do decide to file a charge of discrimination with the EEOC, you could help or hurt your case depending on what you say in your charge. Consequently, I suggest that you confer in person with an employment lawyer. Good luck.Ask a similar question
