Yes I should get paid my current salary for my current work. Feedback on my work is that it is "Good" which means the employer is happy paying me for my contributions. I'm not being paid for my labor and time - I'm being paid so long as my employer thinks what I'm giving them is worth it. I'm not grifting anyone - I'm just in an at-will employment arrangement.

Caring about hours worked is for bad managers, plain and simple. The biggest reason to not work in the office is that it's easier to avoid these bottom-of-the-barrel, butts-in-seats leaders. With them out of the way, you're free to tune your output in such a way that keeps your employer happy while also freeing up your life.
