I'm not an expert on the HRA, the previous conservative government talked about repealing it but it proved too onerous to get any kind of agreement on a replacement 'British Bill of Rights'.
I think Reform tend to appeal more to men than women from the polling I've seen, I think they would pass some anti-discrimination legislation to replace the EA, but it probably wouldn't be as strong, and you would see pandering to the Fathers 4 Justice types.
I also think areas such as reasonable adjustments might be scrapped as too onerous for business, or they might be pared right back especially for 'woke' disabilities like Neuro divergence or mental health conditions.
Equally, there was very little previous legislation that protected gays and lesbians, so I think lesbians would lose out- possibly there'll be little to no replacement legislation for them or possibly big holes of exemptions if you can show you personally disapprove of homosexuality because of a religious or philosophical belief- meaning in practice that your boss could suddenly develop religion if they wanted to sack you.
I think employment protections in general will be pared back though, so even straight white men will have fewer employment rights.
