Final answer:
The recommended practice before starting a drug testing program is to clearly establish a policy. This should be understood by all employees and be in compliance with laws. Communication and legal counsel are critical in implementing such protocols.
Option 'C' is the correct.
Step-by-step explanation:
Before starting a drug testing program, an employer should adopt best practices to ensure the program is effective, fair, and legal. The most recommended practice is to clearly establish a policy. This involves drafting a comprehensive policy that defines the purpose, scope, procedures, and consequences of the drug testing program, ensuring it is in compliance with local, state, and federal laws. It's also important to communicate this policy effectively to all employees, so that they understand the rules and implications of the drug testing program.
Additionally, while it is not necessarily a first step, employers may also consider including temporary workers in the program to maintain a drug-free workplace consistently.
However, prior to testing incumbent employees, an employer should seek legal counsel to navigate the complex legal landscape that governs drug testing in the workplace.
Understanding that employment may begin with a trial or probationary period can also relate to drug testing policies. This period is an opportunity for employers to assess an employee's fit within the company, which can include adherence to established drug-free workplace policies. However, it's important to remember that this trial period must also adhere to labor laws and established company policies.
In summary, the key to implementing a drug testing program successfully lies in the clear establishment of a well-communicated policy that aligns with legal standards and the company's values.
