Reasonable suspicion tests must be conducted as soon as there is suspicion to test.
Employers sometimes wait too long because the are busy doing other things or because they are conducting a factual investigation.
The more time that elapses between the suspicion and the test, the more likely it is that the employee will test negative.
Nitro’s Policy reads as such: Conduct a for-cause drug or alcohol test of any employee when a trained supervisor has reasonable cause to believe that the employee has reported working or is working under the influence of a drug of abuse or alcohol. Written documentation as to the nature of a supervisor’s reasonable cause shall be created.
