At the start of the pandemic, I had to learn how to work from home. I've always worked in an office, so losing the commute and coworkers was a big change for me. It only took a few weeks for me to learn that I needed to establish a routine if I was going to get into a rhythm of working from home.
One of the routines I added was to make Friday my "admin day."
After a week full of Zoom meetings and far too many e-mails, I realized that admin work was all my brain could tolerate by Friday. I use Fridays to clean out my inbox and follow-up folder, update my required monthly report, empty out my voicemail, clean up my Trello and Toggl, work on random "I've been meaning to organize this" projects, and set plans for the following week. If there's time, I also tackle my massive professional reading pile and watch webinar recordings.
My organization is back to work in hybrid mode now, but I am keeping my admin Fridays. I found it to be a productive use of my time that was not too taxing on my mental capacities.
What pandemic induced change are you going to keep?
