The original article is about 'people having a baby'. This is language to include transgender males, that is, those who were born female but transitioned to male later on in life. What rights are being taken away? Is your notion of womanhood so fragile that it is bound by Scottish employment policy?
It's government guidance for employers running a business in Scotland. Statutory Maternity/Paternity/Parental leave falls under a reserved competency, so policy has to align with UK-wide law. It's most important that the guide be clear and accurate and direct the reader to the applicable section of the gov.uk doc, which this fails to do. Of course documents should be inclusive of everyone who is impacted, and that may mean being gender-neutral, but not at the expense of usability.
"Having a baby" is ambiguous, especially as "Maternity Leave" refers to an "employee having a baby" and "Paternity Leave" to a situation where "they and their partner are having a baby". Very likely both partners are not pregnant at once, especially not with the same baby, so "having a baby" /= being pregnant.
In order to access statutory Maternity leave and pay in Scotland (and the wider UK) you must be pregnant/have recently given birth. Biodads, spouses, partners, and other parents-to-be can apply for Paternity benefits including some specific options for adoption and surrogacy. When the language manages to obscure that distinction - why? why not just say "a pregnant employee"? - it's not useful to the intended end user.
Normally, people might just assume government incompetence, but the FOIs requested by Nolan have brought this to public attention. IF it 's true that the language was changed because ScotGov was taking unvetted direction from a lobbying group (and paying for it) in return for unrelated benefit, that's concerning no matter what group it is and what change was made.
I don't have a "notion of womanhood" and don't know any women who do (it sounds a bit male gaze-y) but I do have a belief that my government should be somewhat competent and transparent and that the public should hold it accountable if there is evidence of corruption.
