Final answer:
To evaluate the effectiveness of a drug-free workplace policy, consider factors such as pre-employment drug testing, zero-tolerance approach, and mandatory participation.
Step-by-step explanation:
To evaluate the effectiveness of this drug-free workplace policy, several factors should be considered:
- Pre-employment drug testing: The policy's effectiveness can be evaluated by analyzing the percentage of new hires who test positive for drug use. A lower percentage indicates a more effective policy.
- Zero-tolerance approach: The policy should be evaluated based on how consistently and strictly violations are dealt with. A zero-tolerance approach means immediate consequences for policy violations, which can lead to a more effective policy.
- Mandatory participation: The effectiveness of the policy can be assessed by examining the percentage of employees who comply with the policy. Higher compliance rates suggest a more effective policy.
Based on these criteria, evaluating the effectiveness of this policy would primarily involve analyzing data related to drug testing results, enforcement of the zero-tolerance approach, and employee participation.
