Final answer:
The employer should immediately interview the employee receiving threatening calls to assess the danger and take preventative steps to ensure the safety of all employees.
Step-by-step explanation:
When dealing with rumors of an employee receiving threatening calls from a former abusive spouse, the best immediate action for the employer to minimize liability is to: Interview the employee allegedly receiving calls, assess whether there is a danger to her and others in the workplace, and take preventative steps. This approach is proactive and ensures immediate attention to the potential danger, before it escalates. Such preventative steps could include implementing safety measures, offering support to the affected employee, and possibly involving law enforcement if necessary.
It is important to address the situation in a way that ensures the safety and well-being of all employees and minimizes potential risks. Any action should be aligned with legal obligations and the duty of care an employer has towards their employees. Taking swift and appropriate action not only helps the affected individual but also maintains a safe work environment for all.
