My immediate thought was, why are they moaning about not being able to get jobs cos it's difficult scheduling with the kids etc? They had 7 kids without a thought to how they would be able to pay for their upbringing. Oh hang on, that's right - they thought, "f*ck it, the state will pay for us to keep popping out sprogs with wild abandon". Maybe they were hoping they could get jobs AND keep all their benefits. And get completely free childcare provision, and perhaps not pay tax on their wages either.
And the daughter applied for 15 jobs and already it sounds like she's given up. Some highly qualified people out there have applied for a hell of a lot more jobs than that and been rejected but keep trying.
