I agree. I'm pretty sure that's just part of sailing and I'm not sure how we'd ever get around those occasional long days. I don't think they're that bad at all until they become a serial problem. I think fatigue is a real issue and if they really cared about safety, there wouldn't be a push for smaller more over worked crews. 6 hours on 6 hours off for 6 weeks is really stupid when you add OT/maintenance hours in there.
On the other hand, I'd love to see how they came up with lose productivity figures and how they measure them and insomniacs in general. It also seems plausible that cyberloafing and insomnia could be related but in the other direction...loafing itself contributing to insomnia. How productive do we really need to be? In my experience, this industry is full of "hurry up and wait" moments...pushing people to meet deadlines that don't make a difference in the end game. Technology also has made many jobs semi or completely automated, regulating humans to being trained monkeys with little critical thought (perhaps a tad cynical, but a real argument can be made), causing a weird kind of boredom and anxiety, which also could cause issues with insomnia. And more down time at work to spend cyberloafing. What a deadly cycle, dun dun dun. People text and drive, that is crazy too!
Finally, the author of this article is a professional seminar giver/motivator. Pay me lots of money to tell you obvious things using big words, slide shows and graphs using cherry picked data. "Instead, I suggest raising awareness through approaches like formal fatigue training, informal educational sessions and material distributed throughout your workplace. Consider handing out sleep awareness questionnaires that get people thinking about their own sleep and whether it needs to be improved." It's obvious information that doesn't need advertising. Consider the productivity lost to listening to some asshole like this waste your time at work because some corporate person was convinced it was a good idea. Think of the solution, not the problem, right? So what...reduce work loads and hire more staff right? Shorten the work week/day? But but but lost potential gdp/growth/investment/mumbo jumbo. lol dream on. We don't need questionnaires, we need political action and social awareness
