Discrimination at Work

I wonder any of you experience discriminate at work that doesn't provide interpreter to your needs? If you do please let me know and feedback on your experience at work. Did you file DFEH (Department of Fair Employment Housing) for your complaint against your work? Have they investigate the situation at work?I would like to share my experience that my work didn't provide interpreter, because the employer assume that I'm very efficient fluent on lip reading, which I disagree wholeheartly. I'm fluent in ASL and can talk, but ASL is my first language. One on one I can do it, but as a group for mandatory company meeting that's impossible, my friend is deaf and I are frustrated that we can't get same information as other employees get. I always asked my co worker who is hearing to explained to me what the situation is about.My friend and I finally decided to file complaint against our work company and report to Union and DFEH, eventually they ignore our responses then we took to the next level by getting the lawyer to filed suit against them. Our lawyer said we have very strong case due to witnesses and violate the ADA law.
