At my last company, we would walk around with our laptops. People would just assume we were looking for a meeting room or had something important to do.
I can’t quite remember what we did at our desks specifically. However, I do remember a guy I worked with used to browse Wikipedia and Tinder.
Co worker and I would book meeting rooms then close it up and play coop bloons
Have a look at online courses. w3school, udemy, coursera have IT related courses if that’s your thing, there are other sites that have online courses too. Free ebooks at gutenberg.org that you can download or read online. Do a search for “text only news”, find a site you like, catch up on the daily news; just looks like a page of text from a distance.
Im the sole IT guy at a non profit. I could probably have a movie playing, but if power shell is open I’m covered. It’s hilarious and glorious.
Leave. Go for a walk, or a coffee, or go home. Nobody knows you aren’t in a meeting room.
If your co-workers are into it, have a LAN party. I used to work at a place that had a daily management-approved kill session. It was good.
I take a 30 to 40 minute walk (2 miles) every day at work. Sometimes it’s to clear my head. Sometimes it’s to think about work. Sometimes it’s to think about not work. No one cares, and if they did, I’d argue it’s time well spent for the company. I can’t get anything done if my brain is overflowing with crap.
Man, a work LAN party would be pretty cool.
