Among many hats I wear, I handle human resources for a transmission re-manufacturing facility with around 35 employees, including ofﬁce staff. Our management asked me to develop a drug testing policy. I checked with our lawyers, who said we could do whatever we wanted since we’re a private company and there are no laws on the topic in our state. I don’t support drug use or any illegal conduct, but I’m wondering how to develop a policy that doesn’t seem overbearing. I’m also sure a few great employees will have problems with this because I’ve heard innuendo about what goes on during their garage band practices after work and on weekends. We haven’t had any problems on the floor or in the office that I can see. Where do I start?
Like the compass that identifies north but shows all 360 degrees, the answer depends on where you want to go. If the object is to root out drug use without regard to whether it affects performance, then test frequently, randomly and, of course, before employment. But drugs vary in their ability to be detected, and you may catch 100% of the casual marijuana users and few of the users of hard drugs such as cocaine. The reasons are chemical. The evidence of marijuana use stays in the body for weeks, well after the effects have worn off. Cocaine, however, leaves the body in days. The result could be that a random test on Tuesday catches your star employee who smoked marijuana three weeks ago in the privacy of his basement, but misses the cocaine user who put his paycheck up his nose at the bar Friday night and was planning on selling the tool holder he stole from the floor Monday.
Your question raises broader concerns about the involvement of employers in the private affairs of their employees. Drug testing is common because it is easy and convenient. (If only identifying terrorists was so easy.) But drug testing may not reveal much about employee performance in the workplace. Spouse abuse and drunk driving are also criminal acts, which many would say are much more harmful, at least to others. At a minimum, both demonstrate respectively poor judgment and lousy impulse control, not qualities one wants in a working environment. But you probably aren’t considering putting breathalyzers in employee cars or asking spouses to certify workers as non-abusive. That would cross the line for most people.
