its nice working in government, but at the same time, there are some serious arseholes in there that are semi institutionalised and you will want to kill with a broken coffee mug.
the other thing about government is that it doesnt matter how good you are at your job - it comes down to internal politics a lot more, which is something that drives me mad - i like to work hard, and by paid harder, NOT just sit there and not rock the boat while i suck at a teat
if there is the possibility of advancement within your current company, or the chance of you going out on your own and working for yourself (which is where youll make that extra 10k in a month) then id stay where you are and start repositioning yourself to facilitate that happening.
also, 3 day weekends every weekend are excellent for your social life and general wellbeing. i think that 5 and 6 day working weeks are shit, and turn you into a soulless wraith of a human being unless youre working for yourself. money sometimes just isnt worth that much.
a half hour commute to work sucks a bit though. sell your house and buy another one, youve been there for a decade aap, wtf are you thinking lol - if i knew id be at one job for ages id move into the same street, and use the extra time/fuel saving to buy another house, yeesh
