Final answer:
Mergers and acquisitions often fail due to culture issues stemming from the difficulty of combining different corporate cultures, leading to employee stress and decreased morale.
Step-by-step explanation:
Mergers and acquisitions often fail because of culture issues. When two organizations combine, whether through a merger or an acquisition, there is a blending of different corporate cultures and operational systems. The required integration can lead to significant organizational stress and challenges in unifying disparate teams. Employees may struggle with adjustments to the new corporate culture, leading to decreased morale and productivity, which contributes to the failure of the merger or acquisition.
