There's a lot of negativity on MN about being an academic, I know it's a tough jobs market out there, and a lot of it is luck, but the way I look at it someone has to be lucky, and if you are well-qualified, have good publications and look REFable, then I think you will pick something up. I've worked in a very stable environment once I got my foot in the door and haven't had to move around between unis. I also really like my job, in fact, I would say I love it, which isn't that common among most people I know. I haven't had to leave the country, I had small children when starting out so simply couldn't.
The things is- there are disciplinary areas which are saturated, and areas which are still growing and where you can get your first shot and go from there. I would be reinventing myself to make sure I fitted in with one of those areas where there's still room for growth. Many academics are very purist and only want to do their particular 'thing' even though their 'thing' isn't funded at that moment. The ones I know who have done best are super-flexible and will move departments/disciplines to get work.
I honestly think it's a family friendly job as well, once you have a permanent post in one place. I took the afternoon off yesterday to do something different, and make it up on weekends. There aren't many jobs like that.
I don't disagree that there's long hours, job instability due to short term contracts, pressure, too much admin, but that's what I hear from pretty much all public sector workers at present, and lots of my friends have been made redundant/been on 2 year contracts out of academia.
It's like if you post 'shall I be a teacher?' on MN. Everyone will queue up to tell you it's terrible, worst idea ever, all escaping, but actually lots of teachers quite like their jobs and it's as good a career as any, with reasonable holidays to break it up.
These mythical easy jobs with high salaries with family flexibility living in one location with final salary pensions don't exist anywhere anymore, it's not just the academic sector.
