Anyway, if I were the OP I'd be worried that YC might be more concerned with PR damage control than justice for a handful of low-level employees. For some companies, that has meant discrediting the complainant and building a paper trail against them. (EDIT: I'm not referring to any YC company, just companies in general.)
Are there any guarantees you can offer for whistleblowers?
if we were concerned about PR damage, we'd handle this a very different way. just want to help if possible. you should see some of the flames we send our portfolio companies when they do something wrong :)
