I read r/financialindependence from time and time, and it's not uncommon for me to read about people who have nothing to do at their job. From their account, they ask for more work, but nothing comes, and they spend their days redditing and watching youtube. Thus, they want to retire ASAP as they find this mind-numbing. This is completely bewildering for me. All managers I've had were always eager to pile on more work on my desk when I was starting to look like I was finishing something, sometimes to a fault. Is it a US thing? Have you guys experienced something like that? What is it, something like having to keep people around to justify budgets?
