It is also vital to review HR practices to ensure that employees are trained well and that the proper people are hired for the job. The target companies’ HR policies and compliance with labor laws make it worthwhile to use a human resources due diligence checklist for acquisitions so as not to face penalties for possibly depriving employees of their basic fundamental rights.

    HR is in charge of hiring; if the operations are deemed ineffective, the workforce could underperform, possibly disrupting the operations of the acquiring company.
  • Employment Due Diligence
    An essential component of the M&A HR due diligence checklist is examining possible risks and liabilities to protect the company from litigation, ensuring that no employee will harm the company’s image.
