"Another criticism of corporate culture levelled by the book is that offices have become interruption factories. People are working longer and later because they cannot get stuff done at the office any more. At a conference attended by 600 people, the authors asked how many had recently enjoyed 3-4 hours of uninterrupted work; only 30 hands went up."

That's my main complaint all the time and somehow managers just shrug it off as if there is nothing that can be done. Interruptions plus constant noise make real focused work almost impossible for me.
