You wouldn't even have to look busy
I have a weird workplace fantasy of having a job that would essentially pay me to do nothing. "Nothing" meaning surfing the internet, watching TV or movies, or reading books and magazines. Maybe occasionally there would be someone to help or some button to push, but 90% of the job time would be downtime. You wouldn't even have to look busy, just as long as whatever the job is gets done. Do such jobs even exist?
