... but also there is a shocking amount of paperwork involved with most jobs. Does your job deal with money? There are ledgers and piles of invoices to handle. Does you job deal with building things? There is paperwork for acquiring, storage, and tracking of materials, and then more paperwork for the storage, sale, and distribution of finished products. Do you build experimental shit? All of that materials nonsense is still there PLUS now you have math and extremely detailed models to do to make sure your thing works. Over and over. Along with a whole lot of data for every test run, and then a lot of math and comparing numbers.
Is your job talking to people? Welcome to the world of correspondence, which, yes, a lot is verbal, but just as much is written, not to mention all bullshit to set up to maintain those networks and keep updated on any various projects or special interest groups that may be relevant, plus any/all reports required to keep your superiors (if you have any) updated on progress. Business communication counts as paperwork (where are my office workers out there who have spent three hours on an email so you dont get fucking roasted later, or so your project gets approved?).
Do you have a military command? Omg welcome to paperwork central (as confirmed by a friend of mine who is an O4), because everything needs to be tracked, and all things run on bureaucracy.
Lawyers? Holy FUCK the paperwork. Court documents don't write themselves, and there is a LOT of specific language, AND it needs to have references cited (there was a pretty spectacular couple of court case fubars recently about a couple lawyers trying to us chatgpt for it and fucking themselves and their client over HARD).
Are there folks who are "important" enough that they can push off any and all paperwork onto minions? Some, but they tend to be few and far between, and even very powerful people often like to personally ensure that said paperwork is being done right, which at least requires a review. Get enough projects going and employees, and even a basic glance over of each team's work just to make sure that the end product isnt a steaming pile of shit can turn into a LOT of reading. And potential editing, too.
So. Like. Yes. The mindless paperwork that a lot of fic authors use to fill in the narrative gaps in fic is amusing and sometimes ridiculous, especially if the character.in question doesn't have a 'job' per se, they just go DO STUFF. And yeah, there are definitely characters ans stories that excess paperwork doesn't make sense for.
But a lot of the background busywork is based in what a lot of jobs are really like. And the more action-based a character's job is (ie a mechanic fixes things, a jedi talks to people and potentially stabs them, a race car driver drives cars), the less happy they are likely to be about doing any required documentation, invoicing, or book keeping to sustain that job.
