I'm not sure why you're getting downvotes. A couple of thoughts: Phrasing such as "a minority" might be seen as unfavourable.

However, I do agree with your point that discrimination in employment can indeed be very hard to prove for individual cases, even though broader statistics may illustrate that it occurs.
