At the moment I work five minutes from home in a job I love with great people. I've only been there a year but all the feedback is that I've transformed the place and they don't know how they managed without me 
I have 2 DC currently doing A levels and GCSEs so they're old enough to be left but it's still good to be around when they need me, have breakfast together and be home for dinner etc. DH works long hours, so most home stuff falls to me. I earn £39k
A similar job advertised with a starting salary of £62k, but it's about a 1:15hr commute which would cost around £5kpa. I don't "need" the money although it would feel good to be putting a bit more by for retirement.(we're 50)
Worth the much longer day?
