Not necessarily true.

It's a an employee's duty to bring any abnormality to their superior, and then let them make a decision.

Sometimes something anomalous to a newer employee is actually normal, and an experienced superior knows about.

But sometimes letting an anomaly by doesn't get caught to later, since people further down the line/process aren't looking for or see them. And it's not until the product/process reaches final testing that they become aware. Thus it being cheaper to have stopped the line sooner. And 'punishment' being more severe than simply reporting a mistake or anomaly in the first place.
