Drug testing may help you save money by identifying abusers early on so they can receive treatment. It's usually less costly to treat employees than replace them. Before starting a drug testing program you must decide: who will be tested and when; how to educate employees, maintain reasonable privacy, and provide assistance; and what laboratory to use and what drugs and the level to test.
Testing may be appropriate as part of a routine, periodic physical examination. It may be warranted for employees who perform tasks directly affecting public or co-worker safety and for employees in sensitive security positions. Testing is also appropriate after accidents that indicate impaired performance. Random testing is seldom found acceptable unless warranted by a compelling goal with neutral selection criteria used.
Employee morale will be strained by starting a drug testing program. Before testing, discuss with employees the need for the program and how it will be administered.
