Ian, Ian. I spent years on the road mate, never got stressed, no one had enough money to pay me to get stressed
(and still don't)
Having said that, it takes a particular kind of spouse to handle that sort of life style. My ex did for many years and when we finally split up, my travelling days were over and other factors were involved. FIFO is not for everyone, and I much prefer going home to my own bed at night nowadays.
But gee, I had fun
If you start getting stressed over the job, give it away, no job is worth it. You do your best, and if your boss is stressing over it, thats his/her problem.
Being the Chief Engineer is not the end mate, there's a bunch of bean counters out there trying to give you a hard time too.
As a lowly supervisor I reckon there was more freedom of what to do and when than our Chief Engineer, and I didn't have to sit through boring 4hour meetings. Just went out there and did the job.
Cheers
Bill
