Which of the following actions should an organization's security managers consider to deter and reduce opportunities for employee drug use in the workplace?

This option fails to address the underlying issues related to drug use in the workplace. Ignoring recent incidents may lead to a culture of complacency and could undermine employee trust in management's commitment to safety and well-being. Without taking action, the organization misses the opportunity to educate and protect its workforce.

While this option may seem like a decisive action, it can create an atmosphere of fear and mistrust among employees. Termination without clear communication and support can lead to low morale, legal issues, and a failure to address the root causes of drug use. Additionally, universal drug testing may not be effective if employees lack understanding of the policies governing drug use.

This approach could be perceived as invasive and may damage workplace relationships. Undercover investigations may also lead to a negative work environment filled with suspicion and paranoia rather than fostering an open dialogue about drug use. It does not promote proactive measures such as education and policy communication.
