it would have been better had your dh signed on not you.
i think they were wrong to advise you otherwise.
I have friends who are in a similar situation, but as he is more experienced and employable he claims for them as a couple.
I heard of a certain borough offering easter eggs as prizes for hitting sanction targets.
One woman whose dd was sick and she couldn't get to a JSA meeting, lost her bens for a week!
Maybe the sanction maker got a Kinder surprise for that.
