Buying a business feels like acquiring assets. In reality, you are also acquiring a workforce, a history of employment decisions and the legal obligations that come with both. For Buffalo and Rochester-area businesses considering an acquisition, the employment law dimension of due diligence deserves as much attention as the financial one. What you do not find before closing can cost you significantly after it.
Why employment obligations follow the business not just the seller
The structure of an acquisition affects which liabilities transfer to the buyer, but employment obligations often follow the business regardless of how the deal is structured. In a stock purchase, you step into the seller’s position entirely, inheriting their employment contracts, their wage and hour history and any pending claims or investigations. In an asset purchase, you may have more flexibility to limit what you assume, but if you continue the same business operations with the same workforce, New York courts and regulators often treat you as a successor employer with corresponding obligations.
New York’s WARN Act applies to employers with 50 or more employees and requires 90 days advance notice before a plant closing or mass layoff. A separate federal threshold applies to larger employers. If your acquisition involves restructuring or reducing the workforce, understanding your WARN Act obligations before the transaction closes prevents costly surprises afterward.
What employment due diligence should cover before you close
A thorough employment review before an acquisition gives you a clear picture of what you are taking on and where the significant risks lie. Here is what that review should address:
- Existing employment agreements, including any non-compete, non-solicitation and confidentiality provisions that the seller’s key employees have signed and whether those agreements are enforceable under New York law as currently drafted.
- Worker classification practices, including whether the company has classified workers as independent contractors in ways that may not hold up under New York Department of Labor or IRS standards, which can create retroactive wage and benefit liability.
- Any open or recently resolved wage and hour claims, Department of Labor investigations or employment discrimination complaints that the seller has not fully disclosed.
- Collective bargaining agreements, if any, since the National Labor Relations Act may require the acquiring business to honor existing agreements with unionized workforces even after the transaction closes.
Each of these areas represents a potential liability that proper documentation review can identify, quantify and address through the deal terms before closing rather than through litigation after.
How documentation review creates cost certainty for buyers
The goal of employment due diligence is not to find reasons to walk away from a good acquisition. It is to understand exactly what you are buying so you can price the deal accurately, negotiate appropriate representations and warranties from the seller and structure indemnification provisions that protect your investment if undisclosed liabilities surface after closing.
