A book I’ve really liked recently was Will You Please Just F*ck Off, It’s Our Turn Now: Holding Baby Boomers to Account, by Ryan Heath. It’s about how baby boomers won’t admit when their ideas are old.
Here is a great example of this problem: Jack Welch (and Suzy Welch) writing ridiculous career advice that assumes generations X and Y have the same goals and aspirations that Jack Welch did. But he is old (maybe too old for that spritely wife Suzy) and definitely too old to be telling people to work like he worked, because no one wants to anymore.
Welch tells people to stay with a bad boss at a good company instead of going with a good boss to another company. The assumptions behind this advice are outdated. Welch assumes people usually stay at jobs for more than a year and a half (not true). He assumes everyone is hanging around to get a promotion (not true). He assumes people care more about a company name than what they learn there (really, really not true).
For a tirade against the continuous flow of irrelevant advice from people like Jack Welch, read Ryan Heath.
