£6 an hour at 40hrs a week is about £870 a month after tax/nat, it's not a lot for working nights
also if you got kids, you will have to see if you can claim tax creds to pay for child care, and the inconvenience of not seeing your hubby and kids at normal hours can cause problems.
but as you say, its better to be working than claiming, many employers thou offer only the minimum wage, and by the time you've paid your bills, got to work, you could well have nothing left
old adage - a decent days pay for a decent days work
