I've seen this happen first hand, albeit with far lower stakes. I was a wire puller in a factory that refurbished subway cars. High voltage cables cannot have any breaks in insulation because they're carrying a huge amount of power and you could get shorts and fires. Our supplier frequently shipped damaged cables. Our manager tried working with them to change their packing and shipping method to prevent this, but it still kept happening and it would cause serious delays on the line. Our manager was under serious pressure from the top staff to straighten this out and would get livid if a new batch of cables came in damaged, often blaming us for improper handling. Eventually employees learned to "fix" cables coming in with heat shrink and electrical tape to keep manager happy. This was dangerous and when eventually discovered by quality assurance it became a big issue. Manager was moved somewhere else.
