Random / Periodic Drug Testing

Random testing or periodic testing is usually performed quarterly on a small percentage of current employees who have been randomly chosen by a computer. Each employee has the same slight chance to be chosen each quarter. This process has proven to be helpful in maintaining a Drug Free Workplace. The employee’s knowledge that there is a small chance they may be tested at anytime has been shown to be a deterrent to drug use. Random testing has been the government standard used by the Department of Transportation for all commercial drivers. It has been shown that, when it is clear there is no random or periodic testing after the pre-employment drug test those who are inclined to use illicit drugs often will continue to do so.
