The results may be stunning to non TGs but to any TG who has gone looking for work, the results support what they already know. And for those who transitioned at work, it's not uncommon to see a hero to zero scenario unfold.
Employers will discriminate if they don't like you. They all do it. The ones who get reprimanded for it just learn how to do it better the next time. Laws are put in place, company attorneys tell their clients how to get around them and nothing changes. Illinois has had TG protection laws on the books since 2006 but they aren't enforced. The department of human rights, the agency that reviews discrimination claims, just says, "Insufficient evidence" and it's gone. It's rare to see them find on behalf of the claimant. And employers know that.
Discrimination won't end until society has a problem with it, a real problem, not just because it isn't politically correct.
