Why is the presence of noise cancelling headsets considered a symptom of something being wrong? Most often, I like to have a mix of time spent interacting with coworkers and time spent working “by myself”. I like to be accessible to coworkers and have coworkers accessible to me if I need their assistance, but I don’t necessarily want their full attention all the time, right? I kinda expect the office to be a bustling place. Not loud and shouting all the time, but just a lot of activity of people discussing things.
