Like most things in life, it's certainly not black and white.
Larger companies with dedicated HR could benefit from a menopause policy - it would certainly make them more attractive to work for. However, when I first hit perimenopause and asked HR for support I was told I had poor emotional intelligence and needed to work on myself to make it easier for others to work with me (eventually I left). Smaller companies tend to know their staff better and can be more compassionate, however, they can't necessarily afford to offer the support they'd like.
I think women are discriminated against in the workplace on many levels. If you're of child bearing age a male candidate will be preferrable, when you have children the concept of needing to take time off work to look after them when they are sick is often met with resistance (although on the flipside, I once advised our line manager that a male colleague was trying to get hold of him to advise that his daughter was off sick and he had to take the day off - the first thing he said was 'why isn't his wife looking after her'). Don't get me started on maternity / paternity rights. In Scandinavia it is so great to see young fathers meeting for coffee, not just mothers, whereas an American friend of mine was happy to go back to work within a week of giving birth as she didn't want her male colleagues to think she had preferential treatment. Women feeling they have to leave work due to the menopause (as I did) is just the next way we're discriminated against. Personally, I think it is important to have a diverse workforce, so if women are consistently under-represented at all life stages it's bad for business as they are losing those different insights.
Let's not forget that we all experience menopause differently and will have different needs. A simple request like being able to have a fan provided is going to be a lot easier for a firm to deal with than if they need to re-write policy around working hours or absences. I think the debate on home working that has developed since the pandemic will also have some over-laps with any menopause policy.
I hope things do change, however, it certainly won't be easy, and it's much bigger than just menopause. I think it's good that the TV programme has at least encouraged the debate. I also think it's important that women aren't pressured into taking HRT (unless they want to), just because it suits an employer more.
