Final Answer:
For the remainder of the shift on the day of the test or refusal to take a test, the employee should be removed from safety-sensitive duties.
Step-by-step explanation:
According to the Department of Transportation (DOT) regulations, an employee who refuses to take a DOT-mandated drug test or tests positive for a prohibited drug must be immediately removed from safety-sensitive duties. This includes operating a commercial motor vehicle (CMV), performing maintenance or inspection of a CMV, or performing other safety-sensitive duties as defined by the DOT.
The employee may be allowed to return to safety-sensitive duties after completing the DOT Return-to-Duty (RTD) process. The RTD process includes an evaluation by a qualified substance abuse professional (SAP) and the completion of any required education or treatment.
Here is a summary of the steps that should be taken if an employee refuses to take a DOT-mandated drug test or tests positive for a prohibited drug:
Immediately remove the employee from safety-sensitive duties.
Notify the appropriate supervisor or manager.
Conduct an investigation into the incident.
Refer the employee to the DOT RTD process.
Allow the employee to return to safety-sensitive duties only after they have completed the RTD process and have been cleared by a SAP.
Please note that these are general guidelines and the specific procedures may vary depending on the company's policies and the DOT regulations in effect.
