Legal Guidance for Employers During Mergers, Acquisitions, and Layoffs

Business acquisitions, mergers and layoffs have become hot topics in 2025, with nearly 40,000 Americans receiving layoff notices in October alone. During these times of transition, your HR department must be proactive to minimize the risk of employment law disputes.

Even well-intentioned employers can face claims related to discrimination, retaliation, wage-and-hour violations, and WARN Act noncompliance. To protect your organization, HR should work closely with an employer defense attorney who understands the challenges you are up against. Here’s everything you need to know.

Why Employment Law Compliance Is Critical During M&A Transitions

M&A activity can be chaotic, as it impacts every aspect of the workforce, including:

• Job titles and responsibilities
• Compensation and benefits
• Seniority and tenure
• Workplace policies
• Reporting structures

These changes create legal exposure if not handled carefully. Even unintentional oversights can lead to:

• Discrimination claims
• Wrongful termination allegations
• Wage-and-hour disputes
• Retaliation complaints
• Class-action filings

The reality is that risk is involved in any merger, acquisition, or layoff. The good news is that your HR team can anticipate these risks and apply consistent, compliant processes to insulate your business from litigation. Here’s a breakdown of each phase of the journey.

Phase 1: Pre-Acquisition Due Diligence

Efficient employment-related due diligence is essential for identifying liabilities that may transfer to the new entity. With that in mind, your human resources team should review the following:

• Wage-and-hour compliance records
• Pending or past employment claims
• Policies and handbooks
• Union contracts
• Benefits and compensation plans

The topics outlined above represent some of the most complex and highest liability issues you will encounter during a merger or acquisition. While uncovering errors in these categories may not put an end to the M&A deal altogether, it can affect the terms.

Involving an employer defense attorney early ensures that the purchasing company fully understands its employment-related liabilities.

Phase 2: Handling Structural Changes with Employees

Once the acquisition is finalized, your business must determine how to merge teams and allocate resources. Key tasks include:

Job Consolidation and Reassignment

Your business must ensure that all reassignments are based on business needs. These decisions should be applied using a standardized framework that is defensible and uniform. Even minor discrepancies in how people are reassigned can lead to disputes later. Standardization can be especially important (and difficult) when merging two teams with overlapping roles.

Compensation Alignment

There are bound to be pay discrepancies when two entities merge. Inconsistent pay practices can lead to internal complaints, especially if lower-paid individuals are reassigned roles within the new organization but not given corresponding salary increases. Recent pay transparency laws have increased the risk of these types of concerns.

To prevent these issues, your HR team should conduct market-comparison analyses and pay-equity reviews. Addressing compression early can limit the friction between the newly conjoined workforces.

Combining or Refining Policies

Next, your human resources department must determine which policies to adopt, revise, or eliminate altogether. Updated policies should be consistent and address the following concerns:
Anti-harassment and anti-discrimination rules

• Reporting procedures
• Timekeeping systems
• Remote work expectations
• Performance evaluation standards

Without clear policies, company employees could assert that decisions were arbitrary or retaliatory.

Phase 3: Layoffs, Reductions in Workforce, and WARN Act Compliance

Organizational restructuring comes with the territory during an M&A action. Layoffs are often part of this restructuring. Your business must follow strict legal procedures to minimize risk when cutting the workforce. Here are some tips to protect the organization:

• Use objective selection criteria
• Evaluate whether any protected group is disproportionately affected
• Adhere to WARN Act requirements, if applicable

Noncompliance can lead to significant penalties. An experienced employer defense attorney can determine whether WARN applies so that you can notify affected individuals at the appropriate time.

Phase 4: Addressing Communication and Management Changes in Acquisitions and Mergers

Poor communication is one of the fastest ways to turn an M&A action into a talent disaster. Here are some best practices your HR team can use to keep staff in the loop and cut down on speculation:

• Provide consistent messaging from day one
• Ensure any statements are authorized and reviewed by legal
• Train supervisors on what they can and cannot say
• Maintain confidentiality around pending M&A decisions

Additionally, you could publish FAQs or briefings to increase transparency. Being open and honest with the entire workforce can reduce friction during a business merger or acquisition. Any miscommunication may be used against you if an employee files a dispute.

Phase 5: Monitoring Business After the Merger

Even after all of the shuffling is complete, your HR team needs to engage in ongoing diligence. Here are a few ways that human resources can follow up to protect the business:

• Monitor for any complaints of retaliation
• Reassess job classifications after 90 days
• Review the impact of supervisor training and offer remediation as needed
• Address newly emerging performance issues after the merger
• Evaluate whether the reduced workforce can adequately meet the needs of the business

Remember, issues can still arise months after a merger or acquisition has been completed. Being proactive limits the risk of legal action against your business and promotes better morale.

If your business is sued or faces allegations of wrongdoing, partnering with an employer defense attorney is crucial for protecting your reputation and bottom line.

How an Employer Defense Attorney Can Offer Legal Advice to Protect the Organization

Working with an employment litigation lawyer provides your HR department with valuable legal advice and insights, such as:

• Litigation risk analysis
• WARN Act compliance guidance
• Review of severance and release agreements
• Training for supervisors
• Support during due diligence
• Defense against wrongful termination, discrimination, and wage-and-hour claims

A seasoned legal team ensures that you follow defensible, consistent, and legally compliant processes.
