Indeed. It is of course often very risky for an ordinary employee to report this kind of thing. A fairly large proportion of middle managers react in a very hostile way to something they perceive of as an attempt to make them look bad in the eyes of senior management. They certainly do not see it as the "shop floor prol" doing what might be a very considerable service for the company.
