Thing is, the OP, despite being a Carer, HASN'T said that she expects not to work. What she HAS said is that both her and her DH are currently seeking FT work, then whoever is still unemployed will then look for PT work, so as to still be available to care for their DS with Autism.
That's NOT the actions of a scrounger, or someone not wanting to have employment. Those are the actions of a family that really wants to support themselves, whilst still being able to care for their DS with Autism.
