Final answer:
Managers may fail due to bullying behavior and insensitivity to employees' feelings, or due to a lack of necessary technical skills, whereas strong delegation skills and effective leadership and communication abilities contribute positively to managerial success.
Step-by-step explanation:
Managers at companies may fail in their positions or derail for a variety of reasons. Among these, bullying employees and being insensitive to their feelings is a significant factor (a). A manager who lacks the required technical skills for the job (b) can also lead to failure due to incompetence in handling job-specific duties. However, being excellent at delegating tasks (c) and having strong leadership and communication skills (d) are qualities that contribute to a successful management career and thus do not lead to failure or derailment.
In considering these situations, the impact of poor management on both the morale and productivity of employees is evident. Managers who fail to provide constructive feedback, clear guidance, and opportunities for development can hamper a business's capacity to thrive. Moreover, the personal growth and career development of individuals within the company are significantly influenced by the managerial approach and behavior.
