As I mentioned here, it's important for me to maintain somewhat structured "office hours" while working remotely. I find it hard to get anything done if I allow myself to do non-work tasks during work hours.
That said, I do work non-traditional hours 3 days a week. My non-traditional hours are structured--but they don't happen in the regular 9-to-5 windowI do this because it allows me to spend a chunk of time with my son in the middle of the day and it allows me to avoid having to pay for childcare, which doesn't really fit in my budget. I chronicled one of my non-traditional days here: https://www.doublefourteen.com/post/a-day-in-the-life-of-a-work-from-home-mom.
I'm really curious to hear from other remote workers that regularly work non-traditional hours. How do you make it work? Why do you work these hours? Perhaps most importantly, how do you make sure you get enough sleep?
