Well you have gotten a very different view of faculty than I have. I concede that my experience is only with myself, those in my department, and to a lesser extent, those in my College.  You have had a view from 30,000 ft. I have never experienced (in my department) a full-time, 3-1-1 faculty member that was working less than 40 hours a week (on average). If someone was "phoning it in" we'd be the first to jump down their throat, because the rest of us would be picking us their slack.  Moreover, we are a proud bunch...if there was a slacker among us, the shaming would be vigorous.
