How many people would ever look at the nearest large pane of glass whilst sitting at their desk and wonder whether it were safe? Some might, but evidence suggests that nobody gives it a second thought. Particularly in the workplace. When posing this question in workshops and presentations, the common reply is “Of course it must be OK. If it weren’t, they wouldn’t allow it, would they?”You would be right to think that. Alas, theory and practice are actually worlds apart.
