Death Inc

So my factory will be closing in October, yet another industry that will be lost to our economy with little chance of return.
I am due redundancy in October but will likely be remaining as a contractor to pull the equipment apart to send to the Chile factory, or into storage or in the bin nobody knows, and maybe go to help install the machine in its new home.
If I stay on I will probably be on nearly 2 times the money for 3 to 6 months depending on how the guys involved manage to milk it out.
I had an interview today and have a second interview on Tuesday, seems likely I will get the job for similar money to what I am on now.
If I take the job I will be keeping it quite until I have my redundancy letter so they don't try to delay my departure to ensure my participation.
Since I have more knowledge about the machine than anyone else and my being involved is to everyone else's advantage.
So should I take the job if offered. If they offer me extra money to stay when they figure out I'm jumping ship when does it pay to stay and hope for another job just as good to come up later given the following
I am competing against guys with degrees (I  don't have one)for jobs that prefer degrees, or taking a lower position and 25% pay cut or find the few high paying jobs that are there

Carpes,

This is a hard one, i would prefer you asked it in the ask chalice section as he is our own in house oracle with all the answers...

You and I dont have our jobs becuase of uni degrees, we have it for the retention of knowlegde our jobs have given us.

You need to look at the bigger picture, your wife and family, whilst it is easier to watch all these people with there fifo (fly in fly out) life styles, more money than sense, and no money for rainy days.

I dont have and wont have the magic answer, only chalice and you have these powers.

I've gone down the stability route, it seems to have paid off. i have no great dept, i am not too far off owning my home, and i have a secure job that they keep up skilling me in and paying me extra money for, it's taken a long time, but at have been working for 15 years and i have mates that have only worked for basically 8 out of those last 15, sure they get the new car every few years, go on holidays n shit, but they aren't financially secure have no savings, little super and each new job means they have to start from the bottom again. as far as i can tell i am by far better off. take the longer view mate, get a name for your self as the reliable goto guy and the jobs will come to you... good luck mate i know you'll make the best choice for you as your the only one who can.
