I am paid £17 per hour for my time. NMW will be £10.42 per hour come April. My pay slip claims my hourly rate is £25 though. My salary is £25k. If I worked the same hours at NMW, my salary would be £16,255
NMW is currently £9.50 per hour - you can't uplift one side of the comparison without uplifting the other. The Scottish Government have already offered an uplift of 6.85% for the lowest paid teachers - 5% for most.
on NMW I’d take home £1200, which includes the sliding scale pension payment I’d make if this NMW job was part of the same scheme
As a teacher in Scotland your employer pays 23% of your pensionable income towards your pension;

I also lost out on 5 years earning while I trained to be a teacher
Clearly you are going to be far better off over your working life on an FTE of £40,000 plus - compared to someone on NMW; better choice of where to live (mortgage/rent), better pension, access to credit (for cars, home improvements etc.) ...
Oh, and, on NMW I’d be entitled to £90/week towards childcare costs, and right now I get £0
So actually, I’d be better off on NMW
Is your doppelganger a single parent? But you are not. I don't see how you will be better off financially ditching your partner and his salary.
