Usually you get compensated for time spend at work, not for your labor directly.
sounds like you have one of those jobs in which you just need to show up and you don't need to actually do anything.
In most jobs, if you're not actively busy at all times working, it's either because you're dead, or about to get fired, because the work never ends. If you just "show up," but don't do anything, you're not gonna last long.
Have you ever been a Security Guard? Easiest shit ever.
