I work with a number of people in my office who do completely different things than I do. If we didn't make time to just talk about whatever between the times we work, we would probably never need to speak to one another. That being said, there is a benefit to having 'non-productive' communication with colleagues during working hours, because it builds trust and rapport. These become infinitely value at seemingly unexpected times, and it's difficult to calculate an ROI on asking your colleague how their weekend was.
