Layoffs are one of the hardest decisions a business owner makes, and one of the easiest to get legally wrong. A reduction in force that isn’t planned properly can expose your company to notice violations, discrimination claims, and costly litigation, even when the layoff itself was a reasonable business decision.
Here is what the WARN Act actually requires, where smaller employers are still at risk under state law, and how to plan a reduction in force that holds up.
What the Federal WARN Act Covers
The Worker Adjustment and Retraining Notification Act requires employers with 100 or more full time employees to give 60 days advance written notice before a plant closing or a mass layoff. It applies in two main scenarios.
A plant closing occurs when a facility shuts down and 50 or more employees lose their jobs within a 30 day period. A mass layoff occurs when a company lays off 500 or more employees at a single site within 30 days, or lays off at least 50 employees representing a third or more of that site’s active workforce.
If your business has fewer than 100 employees, the federal WARN Act doesn’t apply to you. That’s where many small business owners stop paying attention, and that’s a mistake.
Why Smaller Employers Aren’t Off the Hook
A growing number of states have their own version of WARN, often called mini WARN laws, and many of them apply to employers with far fewer than 100 employees. California’s WARN Act, for example, applies to employers with 75 or more employees and covers layoffs affecting as few as 50 workers at a single location, regardless of what percentage of the workforce that represents. New York’s version applies to employers with 50 or more employees. New Jersey requires severance pay in addition to notice for covered layoffs.
If your business operates in any of these states, or several others with their own notice laws, you may have obligations well below the federal 100 employee threshold. This is the single most common blind spot in reduction in force planning.
Steps to Plan a Reduction in Force Properly
Determine which laws apply. Check the federal threshold, then check every state where affected employees are located. A layoff that doesn’t trigger federal WARN can still trigger a state requirement.
Choose selection criteria before you choose names. Decide the objective factors you’ll use, performance ratings, tenure, role elimination, before identifying specific employees. This sequence matters because it protects you from claims that criteria were built around a predetermined outcome.
Run a disparate impact check. Once you have a list of employees selected for the reduction, compare that list against protected categories, age, race, gender, disability status. If the layoff disproportionately affects one group, even unintentionally, you need to understand why before moving forward.
Document the business rationale. Keep a clear record of why the reduction is happening and how selection decisions were made. This documentation is often the deciding factor if a former employee later challenges the layoff.
Time your notices correctly. If WARN or a state equivalent applies, the notice period is not flexible. Missing the window by even a few days can expose you to liability for wages and benefits for the entire notice period.
Prepare severance and benefits information in advance. Employees losing their jobs need clear answers about final pay, COBRA continuation, and any severance offered. Having this ready before notices go out prevents confusion and reduces the risk of disputes.
Communicating the Reduction
How a layoff is communicated matters almost as much as the decision itself. Give affected employees direct, honest information about why the decision was made and what support is available. Avoid vague language that leaves room for employees to fill in their own explanation, since that’s often where discrimination claims start.
How HRDelivered Helps
Planning a reduction in force touches payroll, benefits, compliance, and risk management all at once, and getting any one piece wrong can create liability that outlasts the layoff itself. HRDelivered’s HR consulting and compliance support helps you check the right thresholds, document the process correctly, and manage the payroll and benefits side so nothing falls through the cracks during a difficult transition.
