Will this be my last full-time tech job? Almost certainly. I celebrated 15 years here a few days ago, and will reach retirement age (66 in 2024 in UK) in less than 10 years. Despite legislation against age discrimination in employment being in place for several years now, little has changed. It is very difficult for an older worker to land a new job.
On the plus side, my current employer is running a stable, profitable business, with relatively good conditions of employment - staying here is not a hardship. And they will still be trading profitably in 10 years time. But I still plan to retire when I reach retirement age. I have plenty of interests ouside work which I don't have enough time for.
I have always feared having to work until I drop. I do not want that pressure, so I have always paid into pensions, so that I can retire into comfort, not poverty.
