Hawaii Dislocated Workers Act (HDWA) Compliance During Mergers and Acquisitions

Current as of: October 20, 2026 Mergers & Acquisitions (M&A) Hawaii
When acquiring or merging companies in Hawaii, the Hawaii Dislocated Workers Act (HDWA) applies to businesses with 50 or more employees. You must provide a strict 60-day written notice to the state and affected workers before mass layoffs, or face liability for back pay and benefits under state law, in addition to statutory dislocated worker allowances.

Mergers and acquisitions (M&A) often lead to corporate restructuring. When two companies combine in Hawaii, overlapping departments are frequently downsized to save money. While cutting costs is a standard business practice, doing so without following Hawaii's incredibly strict labor laws can result in massive financial penalties and devastating lawsuits.

Hawaii is a highly pro-worker state, and its local plant closing laws are much more stringent than the federal standards. Navigating the legalities of layoffs during an M&A transition requires exact timing and a deep understanding of state labor statutes. Below, we break down what employers must do to comply with the law during a corporate buyout. We strongly encourage you to consult a dedicated Hawaii employment lawyer from our directory before finalizing any post-merger staffing changes.

HDWA vs. Federal WARN Act in Hawaii

Nationally, the federal 29 U.S.C. § 2102 requires employers with 100 or more employees to provide a 60-day notice before a plant closing or mass layoff. However, Hawaii has its own law, the Hawaii Dislocated Workers Act (HDWA), found in Haw. Rev. Stat. § 394B-1.

The HDWA is much stricter: it applies to any employer with 50 or more employees within the state. Under Haw. Rev. Stat. § 394B-9, if a post-merger restructuring will result in a 'closing' or a 'partial closing' that causes job losses, you must provide a 60-day written notice to the affected employees, their union representatives, and the Department of Labor and Industrial Relations, Honolulu (DLIR). You will typically issue a formal letter fulfilling the requirements of the state, ensuring the DLIR Director is fully informed of the transition timeline.

Industry-Specific Compliance During M&A

Whether you are taking over a resort in Maui, a grocery chain in Oahu, or a production facility in Hilo, your obligations vary depending on the industry and the presence of organized labor.

Step 1: Unionized Hotel Staff and Hospitality

When one hotel brand acquires another, they often bring in their own management and may want to lay off existing staff. In Hawaii's hospitality sector, many workers are represented by powerful unions like UNITE HERE Local 5. You must review the existing Collective Bargaining Agreement (CBA) for a 'successorship clause.' Often, these clauses force the buyer to retain the existing workforce and honor their seniority. Failing to negotiate with the union over the effects of the merger can trigger Unfair Labor Practice charges. Precedents like Gouveia v. Napili-Kai, Ltd., 65 Haw. 189 (HI Supreme Court 1982) emphasize how heavily Hawaii courts weigh collective bargaining rights during employment disputes.

Step 2: Large Retail Chains and Partial Closings

If a mainland retail giant acquires a local Hawaii chain and decides to close three out of ten local store locations to consolidate operations, this triggers the HDWA as a 'partial closing.' Even if the company offers the workers jobs at a different location on the island, if the commute is considered unreasonable, it may still count as a dislocation. You must issue the 60-day notice properly to avoid paying penalties for those specific closed locations.

Step 3: Manufacturing Plants and Food Processing

In manufacturing M&A, buyers often acquire the physical equipment and real estate but plan to shut down the actual production line. If you shut down a facility with 50+ workers without giving the mandatory 60-day notice, Haw. Rev. Stat. § 394B-9(b) mandates that you pay each affected employee full back pay and benefits for each day of the violation period up to 60 days. Separately, under Haw. Rev. Stat. § 394B-10, employers undergoing a closing or partial closing must provide eligible employees with a 'dislocated worker allowance' to supplement their unemployment benefits for up to 4 weeks, a requirement that applies regardless of whether timely notice was served.

Employer Guide: What to Do If Mass Layoffs Are Required Post-Merger

If post-merger layoffs are unavoidable, you must execute a compliant strategy:

  • Count Your Workforce: Determine if you have 50 or more employees in Hawaii (excluding part-time workers who work less than 20 hours a week, unless state specifics pull them in).
  • Draft the Notice: Prepare a formal 60-day notice detailing the effective date of the layoff, whether the layoff is permanent or temporary, and the titles of the affected positions.
  • Deliver the Notice: Serve the notice to the employees, their union representatives, and the DLIR director exactly 60 days before the first termination occurs.
  • Prepare Severance and Allowances: Failing to provide the 60-day notice triggers liability for back pay and benefits under Haw. Rev. Stat. § 394B-9(b). In addition, under Haw. Rev. Stat. § 394B-10, employers must provide eligible employees with the dislocated worker allowance for up to 4 weeks, while ensuring all earned wages and accrued vacation are paid immediately upon separation.

Costs of Non-Compliance

Ignoring the HDWA during an acquisition can destroy the financial benefits of your merger. Under Haw. Rev. Stat. § 394B-9(b), employers who violate the notification rules are liable to affected employees for back pay and benefits for up to 60 days. Additionally, under Haw. Rev. Stat. § 394B-9(d), the DLIR can levy civil penalties of up to $500 per day against the business entity. If employees must sue to recover wages, benefits, or their statutory dislocated worker allowance under Haw. Rev. Stat. § 394B-13, you will be ordered to pay their lawyer fees and court costs. Hiring an M&A employment lawyer at $350 to $600 an hour to properly manage the transition is far cheaper than funding a class-action lawsuit.

How Long Does the Process Take?

The timeline is rigid: you must wait 60 full days from the date the DLIR and the employees receive the formal written notice before you can terminate their employment or stop paying their wages. Rushing this timeline by even one week will trigger statutory liability for back pay and benefits under Haw. Rev. Stat. § 394B-9(b) for the days you fell short.

Frequently Asked Questions (FAQ)

Does the HDWA apply if the buyer immediately hires all the old employees?

Generally, if the acquiring company offers the existing employees substantially equivalent employment without a break in service, it is not considered a closing or mass layoff, and the 60-day notice may not be required.

Do we have to pay severance if we successfully give the 60-day notice?

Even with timely 60-day notice, Haw. Rev. Stat. § 394B-10 requires covered employers to pay the dislocated worker allowance (up to 4 weeks of supplemental unemployment payments) to eligible employees, unless an exception applies such as supplemental unemployment benefits under a collective bargaining agreement. Accrued vacation and earned wages must also be paid upon separation.

What happens if an employee quits during the 60-day notice period?

If an employee voluntarily resigns to take a new job during the 60-day notice window, you only have to pay them for the days they actually worked. You are not obligated to pay them for the remainder of the 60-day period.

Are part-time workers counted towards the 50-employee threshold?

Typically, employees who have worked less than 6 months in the prior 12 months, or who work less than 20 hours a week, are not counted toward the 50-employee threshold under Hawaii law.
