WARN Act Requirements in Maryland: Advance Layoff Notice Rules

The Worker Adjustment and Retraining Notification (WARN) Act, enacted in 1989 and codified at 29 U.S.C. § 2101 et seq., requires covered employers to provide 60 days advance written notice to affected workers, their representatives, and state agencies before implementing a mass layoff or plant closing. The law applies to employers with 100 or more full-time employees (not counting part-time workers under 20 hours per week). A covered event occurs when an employer lays off 50 or more employees at a single site of employment, or 500 employees nationwide regardless of location.

The WARN Act defines layoffs broadly to include temporary or permanent reductions in force, plant closings, and certain sales of business. The 60-day notice period runs from the date written notice is delivered to workers and state authorities. Covered employers must notify affected workers in writing, including notice of the layoff date, reason for the action, and their rights and benefits. Notice must also go to the state's dislocated worker unit and, if workers are union-represented, to the union.

The U.S. Department of Labor (DOL) enforces the WARN Act. Violations result in civil liability: an employer may owe each affected employee 60 days of back pay (based on regular rate of pay, including commissions and bonuses) plus the cost of health insurance continuation (COBRA) for up to 60 days. Class action lawsuits by groups of employees are common. The WARN Act preempts less protective state laws and does not create a private right of action—enforcement is by the DOL or state attorneys general, though private parties can sue in federal court under the Administrative Procedure Act.

Maryland has no state law that supersedes or supplements the federal WARN Act. The Worker Adjustment and Retraining Notification Act, 29 U.S.C. § 2101, applies uniformly in Maryland and is the exclusive notice requirement for mass layoffs and plant closings affecting 50 or more employees at a single site.

Maryland does, however, provide complementary worker assistance through its state dislocated worker program, administered by the Maryland Department of Labor. Under WARN Act regulations, employers are required to notify the Maryland Department of Labor (specifically the Division of Workforce Development and Adult Learning) at the same time they notify workers. This notification triggers access to rapid response services, retraining programs, and unemployment insurance benefits for affected workers. The state agency works in parallel with WARN Act notice to connect workers to new employment opportunities and skill development.

Because Maryland imposes no additional notice requirements beyond WARN, employers need only comply with the 60-day federal timeline and the content requirements specified in 29 CFR Part 639. The state has not extended notice requirements to smaller employers, lower threshold counts, or longer notice periods. Maryland employers covered by WARN (100+ employees, 50+ affected workers at one site) must meet the federal standard; those with fewer employees have no mandatory notice obligation under either federal or state law, though some employers may voluntarily provide notice as a matter of good practice.

Maryland also recognizes the WARN Act's definition of "employment loss" and does not require additional forms of notice or severance beyond what WARN mandates. The state does coordinate with federal authorities on enforcement but does not have a separate state penalty regime for WARN violations. Enforcement in Maryland proceeds through the DOL and federal courts under the WARN Act's remedies (back pay, benefits liability, and attorney fees).

The WARN Act exempts employers with fewer than 100 full-time employees (on a payroll for at least 12 months). Temporary employees and part-time workers (fewer than 20 hours per week over a 12-month average) are not counted toward the 100-employee threshold.

Reductions of fewer than 50 employees at a single site are not covered, even at large employers. The law defines a "single site of employment" narrowly; layoffs at separate facilities may not aggregate to trigger WARN if each facility has fewer than 50 affected workers. A 90-day notice period is permitted in certain limited cases where an unforeseen business circumstance prevented the employer from knowing about the layoff in time—however, the employer must still provide as much notice as possible and demonstrate the unforeseen nature in writing.

Temporary plant closures (not permanent) may fall outside WARN if the layoff does not constitute a permanent reduction in force. Similarly, bumping and laying off of individual employees over time (attrition) rather than a single mass event may not trigger WARN, although the DOL has issued guidance stating that employers cannot circumvent WARN by spreading layoffs across multiple smaller events.

The "falcone exception" permits employers to reduce notice below 60 days if a natural disaster, war, terrorism, or other unforeseeable event prevents timely notice. An employer relying on this exception must provide written notice explaining the circumstances and evidence of the unforeseeable event.

The WARN Act does not require severance pay, extended benefits, or alternative employment—it only mandates notice. Employers who provide notice but no severance have complied with WARN. Additionally, WARN does not apply to strikes or lockouts in the context of collective bargaining, nor does it cover sales of a business if the successor employer retains the workers. Plant relocations within a reasonable commuting distance, if the employer offers substantially equivalent employment, may be exempt from WARN, though the DOL interprets this narrowly.

Step 1: Document everything related to the decision to lay off workers. Keep records of when leadership decided on the layoff, how many employees are affected, which site(s) are involved, and the date the layoff will take effect. If you suspect the layoff will trigger WARN (50+ employees at one location), immediately begin collecting a list of affected workers, their job titles, departments, and employment dates. Calculate the aggregate number of employees in a 30-day, 60-day, and 90-day window to determine if the threshold is met. Preserve all internal memos, emails, and meeting notes discussing the reduction.

Step 2: Determine whether your employer is covered by WARN. Count your company's full-time employees on the payroll for the past 12 months (excluding part-time workers averaging fewer than 20 hours per week). If you have 100+ employees and the layoff affects 50+ at a single site, WARN applies. If you are unsure, consult the DOL's WARN regulations or contact the Maryland Department of Labor. At this stage, communicate internally with HR and compliance to begin drafting notice. Do not announce the layoff publicly or to workers before sending formal WARN notice—premature disclosure weakens legal compliance and can harm the notice process.

Step 3: File WARN notice with the Maryland Department of Labor and affected workers. You (or your employer's HR department) must send written notice to: (1) all affected employees, individually or by job classification; (2) any union representatives of the affected workers; and (3) the Maryland Department of Labor, Division of Workforce Development and Adult Learning. The notice must include the effective date of the layoff, the reason for the action, a general description of the affected job categories, and information on how workers can access unemployment insurance and retraining programs. Send notice at least 60 calendar days before the layoff date. Use certified mail or email confirmation for proof of delivery. The Maryland Department of Labor's address for WARN notices is available at dol.maryland.gov; call (410) 767-2357 to confirm the correct recipient and address.

Step 4: Understand the investigation process and employer obligations during the 60-day period. Once notice is filed, the Maryland Department of Labor will acknowledge receipt and may direct affected workers to rapid response services, retraining, and unemployment benefits enrollment. If the employer fails to provide notice or provides inadequate notice, the state or DOL may conduct an investigation. During the 60-day notice period, the employer must continue to pay wages and provide health insurance benefits normally. The employer cannot lay off workers early or retaliate against workers who ask questions about the layoff or their rights. The DOL has authority to audit compliance and may request documentation of the notice sent, the number of affected workers, and payroll records.

Step 5: Consult an employment attorney if your employer has not provided notice or if you believe the layoff violates WARN. If notice was not given 60 days in advance, you and other affected employees have a right to back pay (60 days at your regular rate of pay) plus the cost of continued health insurance. An employment attorney or employment discrimination attorney can file a claim with the DOL or initiate a class action lawsuit on behalf of all affected workers. Many employment law firms in Maryland work on contingency (no upfront cost if you win). The statute of limitations for a WARN violation is typically three years. Contact an attorney within 90 days of the layoff date to preserve your claim.
