I work from home full time with occasional travel. My employer allows either a half hour or one hour lunch break, based on personal choice. I typically don’t take a formal break instead, I take brief pauses throughout the day (e.g. five minutes here and there to make a coffee, play with my dog, or put a load of laundry on), while otherwise remaining at my desk and working.
Recently, my manager called me to ask why I appear “orange” (away) a lot during the day. I explained that I take small, informal breaks rather than a long formal one. She told me this was unacceptable, even though my approach has not negatively impacted my productivity. In fact, I’m often more efficient this way. I also need to get up regularly as it hurts my back sitting for a long period of time
Other colleagues especially smokers also step away from their desks regularly, but it seems to be accepted for them.
