Just be careful.I wasn't working for 10 wks after my maternity leave ended,as my job is seasonal & it was the winter.Consequently I didn't pay NI,neither was I able to claim any benefits.
Two years later,I was ill & applied for Incapacity benefit for a week & was refused-because I hadn't paid NI for those 10wks two years before.I was fuming,as I've only had 11 weeks without a job in 22 years,so have paid loads in tax & NI,but that made no difference.
