I suppose it all hinges on how desperate your finances are and how stressed your husband is.
I found myself redundant and unable to get back into my sector shortly after I had DD3. Meanwhile the recession hit and DP's self employed income stopped, then halved. We ended up massively in debt. It's terrifying how quickly it happened with 3 small children too 
I took a job - any job and was fortunate to be recruited into the public sector doing call centre shift work. I earn pro-rata about £25,000 p/a due to shift allowances - nights/bank holidays and yes I am working Christmas Day this year.
I look back at my cushy job before - flights to meetings in Europe, writing for a living, high heels, managing a team of 15, every day different and I can hardly believe that was me. But the upside is that with my current income DP is not about to keel over from stress and his earnings are creeping up month by month, we managed a holiday this year, I can pay for new winter boots for the children. And this is much more important than a self fulfilling job at the moment.
Fortunately I am studying for a second degree and will go into teaching afterwards and our finances and my life will be back on track.
Anyway,
What I am saying is - how desperate is your situation?
If it is not then look around for a job you will like, as working in a job you dislike has it's own cost to your health and self esteem (take it from me)
If things are spiralling, if your husband is grey from stress, then yes take any job.
