Why neither the law, nor a helpline, is enough to tackle gender/harassment

I remain puzzled that the Statute of Limitations for many civil offenses such as medical malpractice is four years, while offenses such as workplace discrimination for reasons of age or disability is just five months.

The Equal Opportunity Commission and US Department of Justice are quite vigorous at pressing Americans with Disabilities Act complaints. They just about always win.

But despite that I commonly have standing to file an ADA complaint, because my most-pressing concern when I am denied work over my mental illness is that I find some other job, I always let the timeout expire.

I intend to look into who backed the five month statute - who introduced it to the legislation, who supported it in committee, and who contributed their campaign funding.

The subjective nature of gender discrimination/sexual harassment makes it difficult for not only the law/helpline administrator, but even the victims themselves to ascertain its occurrence. The lack of genuine support on offer to the victims to voice out perhaps is the missing pieces. Thoughts?
