Which of the following is one of the four main activities of HRM?

One of the four main activities of Human Resource Management (HRM) is the maintenance of human resources. This involves implementing practices and policies that ensure the organization's workforce is effectively supported and developed, thereby enhancing employee satisfaction and productivity. Maintenance of human resources includes activities such as employee relations, performance management, employee engagement initiatives, and ensuring a safe and healthy work environment.

This aspect of HRM focuses on nurturing the existing talent within the organization, ensuring that employees are motivated and committed to their roles. It plays a critical role in retaining employees and fostering a positive organizational culture, which ultimately contributes to overall business success.

The other options, while they may have relevance in certain contexts, do not represent the core activities within the typical framework of HRM. Financial assessment pertains more to managing the organization's finances, strategic planning involves long-term organizational goals and directions, and market analysis deals with understanding market conditions and competition, none of which are specifically focused on the management and maintenance of the workforce.
