Final answer:
A key challenge for human resource management during mergers is developing conflict resolution skills to manage the integration of different corporate cultures and the associated organizational stresses.
Step-by-step explanation:
A challenge for human resource management during mergers is developing conflict resolution skills. When companies merge or one is acquired by another, there can be a duplication of services and departments. Integration often requires a reduction in staff, leading to organizational stresses and the need for employees to adjust to changes in culture and workplace dynamics. Human resource professionals play a critical role in managing these transitions, addressing conflicts that arise from merging different corporate cultures and workforce dynamics. Therefore, the effective development of conflict resolution skills is crucial in facilitating a smooth transition and maintaining productivity.
