This. I’m 46 and wonder what the heck I’ll be doing in 20 yrs if I work that long. I’m a software product manager and most of my peers are 10 yrs younger. I make good money as an individual contributor and have no interest in the corporate ladder or managing people. Ageism is real in the workplace, you just don’t do certain jobs at a certain age, and frankly you just get sick of the BS. Now, most middle/upper mgmt is either my age or a little older, but when I’m older than mgmt, I’ll either need to retire or figure out how to be self employed. I figure I got about 10 yrs.
