I work in accounting and there are a ton of 1980s mentalities in this field.
From viewing people as numbers in a column of a spreadsheet to mandatory working in the office, it's pretty clear this field is having a very hard time advancing into the modern day.
The worst of which, for me, is the necessity of paper for many of these people to understand anything. My boss has to, on a daily basis, manually update an excel spreadsheet version of a report that our software automatically generates, print it out, and then package it in a daily financial report binder for review. All of this is because their boss is incapable of running a report and reading it themselves on a computer screen and they “like the feel of the paper” better.
