For a loose example, lets say during a functional check, a flight control was damaged through circumstances beyond the contol of those involved. A member of management will make the call that may require you to undertake a drug & alcohol test. Strange. Because I can recall occasions where individuals were subjected to tests and occasions when other individuals were not for similar incidents. Targeting individuals now?
We asume that the person carrying out the test has been trained to use the equipment and that they understand how to inerpret the results? What if they make a mistake? Will they be tested?
Why do I ask this? Because it is highly likely that it will happen. In fact, it already has.
So what about if management make a mistake? Can we require them to take a drug and alcohol test? Who makes the call when they mess up?
