A few years back I worked for a prominent design company. Our small group (of 4) had a nice little corner of 1/4 of an entire floor. "Oooh, nice, brick walls and people that look busy" I thought when I first joined. Not even a week later, reality started to set it. It was so ridiculously noisy.
And there were, of course, a few people that contributed to everything. I would sometimes get in around 8, it would be quiet and the usual offenders were actually working. From 10-6, it was like, forget it, noise non-stop. After 6, back to quiet.
This became really frustrating and after asking the offenders to chill, I made a trip to HR to ask wtf? HR was basically like, meh, nothing we can do. I ended up wishing those offenders would quit or worse. It was so bad and they were so loud.
After that I was like, never again an open floor plan. It was the worst thing ever and a total sham for those that want to focus and just get things done. Requiring the people whole want quiet to put headphones on only adds insult to injury.
Too bad quiet just isn't valued anymore..
