I just saw on our local news that the drug enforcement agency has been doing surprise drug tests on cab drivers from different agencies because of the increasing complaints of arrogance and misdemeanor exhibited by cabbies these past few months. Amazingly, the agencies they have tested all had some drivers who turned out to be positive from certain drugs and substances. Consequent warning and laying off from work have been implemented on the ones who were tested positive. Are you amenable to surprise drug tests in your places of work? What are your experiences when it comes to this? I'd love to hear your ideas and thoughts.
