If you don’t enjoy your job, then it might be better to get done what is expected of you and enjoy the rest of the time you have to spend butt-in-chair doing so

If you don’t enjoy your job, then it might be better to get done what is expected of you and enjoy the rest of the time you have to spend butt-in-chair doing something else, instead of intentionally piling more unenjoyable work on your platter. Especially if the manager isn’t technical: just don’t tell them you’re done and spend that time doing something else. Of course it completely depends on your work situation and the relationship with your manager, as well as how socially acceptable it is in your organization. I think lots of the people doing it had slacked off in high school and college and gotten away with it. Your relationship with your work and your time is probably much healthier, so I wouldn’t start screwing around during work hours now.
