In discrimination retaliation case, What and How the "Discovery" process in ? and how to reach the best result to prove a case?
I think that you've asked the same question 2 times and already received a good summary of what discovery is about and how important it is.
No attorney can give you a brief answer to your question of "how to reach the best result to prove a case." That is what litigation and trial lawyering are all about. It requires a detailed investigation and understanding of the facts. Likewise, it requires a detailed understanding of the applicable law including the law of evidence. And it requires understanding the art of persuasion. These are things that lawyers to go law school and then train and gain experience for years to master.
I assume that you are the plaintiff. If you have a meritorious case, many lawyers are likely to consider representing you, and in discrimination cases - if you prevail - your attorney has the opportunity to force the defendant to pay at the prevailing hourly rate for the time spent representing you on the case. I suggest you consult with an attorney.
