Which HR team is primarily responsible for assisting top management with high-level issues?

The correct choice is the corporate HR teams, as they are focused on the strategic alignment of HR initiatives with the overall goals of the organization. Corporate HR teams typically engage with top management to address high-level issues such as organizational development, talent management, and leadership strategies that require a broad, company-wide perspective.

This team plays a vital role in formulating policies and practices that support the company's objectives, as well as in ensuring that HR practices are integrated across all levels of the organization. By working closely with senior leadership, corporate HR teams help to guide the direction of human resources in a way that aligns with the company’s mission and vision.

In contrast, functional HR teams specialize in specific areas such as recruitment, training, or benefits, which may not require direct interaction with top management. Regional HR teams focus on issues that pertain to a specific geographic area, adapting policies and practices to fit local needs. Support HR teams typically handle administrative tasks and day-to-day HR operations rather than strategic advice to senior leaders. Each of these teams plays a critical role in the organization, but corporate HR teams are uniquely positioned to address high-level strategic issues.
