I learned this a few years ago, I started taking half the day off because I was remote and they couldn't tell.

And then I thought...what if I just fill that time with another job? So I picked up a 2nd...and then a 3rd.

None of them have given raises to employees in years now because "they can't afford it" or "milestones weren't hit". And that sucks, but I use it to further justify my actions.

To be clear, I never let the team down and I always meet or exceed expectations performance review wise. So I really have zero guilt over this. These particular companies also grossly under pay for the industry so they kind of know that they wouldn't be able to find anyone without paying far more.
