A few confused PPs on here. Understanding of SHPL needed.
What you’re asking is - why can’t there be the same #weeks enhanced SHPP available to your DH as there is mat pay for mothers at his work. Nothing to do with what your employer pays.
If it was equal (at his work), it would enable you to share some of your leave with him (leave, not pay) once your mat pay drops and he could take time off, paid SHPP, while you either return to work or spend some time off parenting together. Right now if you were to share your leave, for him it would either be statutory SHPP or unpaid, making it unattractive/impossible.
Im not aware of any case law where the father has won here. The base line is that companies can pay mothers more/for longer than fathers due to the medical impact of giving birth to a child.
A lot of companies are slowly changing this, faster than legislation is changing, by offering equal SHPP or even just offering equalised paternity pay (no sharing required). Your DH should have a sensible discussion with his employer about this. They’re unlikely to change just because it would benefit him, but if it’s a male dominated company he might want to point out that developing better parental policies shows a commitment to diversity and lifestyle choices, which will aid overall employer proposition and recruitment/retention of women. Allowing fathers the option to share the responsibility of early childcare (by paying enhanced SHPP) enables mothers to return to work and further their careers (important if desired, but even more important if they’re the breadwinner). Only when more companies start doing this will we see gender balance at work start to improve, and we might eventually see a statutory movement.
