I used to work in a company that believed in intensive tracking. Our computers had productivity trackers which used to log our every activity and of the 8 hours(out of 9) that we were billed, we had to show 8 hours of productivity.
Life was hell. We ended up sitting, moving mouses and pushing keys. We used to stay in office for 10-11 hours so that we could complete our fill of productivity, even when there wasn't any work to do. I used to curse the companies who made these kind of tracking software.

My question to you is, would you build such kind of software for money if you knew how is it going to be used? What're your thoughts about it.
