I remember reading a story on Reddit about a guy who managed to do nothing for his job for the last 6 years and just played video games and surfed Reddit the whole time. He eventually got fired when management found out that he managed to automate his job.
I currently feel like this. I work as a security guard and some days I feel like I only do 40 minutes of real work in a 8 hour day and do nothing the rest of the time. I am currently trying to get a remote job so that way it would be easier to not look busy while at home working. Have you had a job where you did nothing for years?
