Connecticut WARN Act

Connecticut WARN Act: complete guide

Connecticut's mini-WARN law, the Business Closing Act, matches the federal 100-employee threshold and 60-day notice period. But it adds something federal WARN does not: an explicit trigger for relocating operations 50 or more miles away. Employers planning a move, not just a closing, must analyze CT WARN separately.

What is the Connecticut Business Closing Act?

The Connecticut Business Closing Act (Conn. Gen. Stat. § 31-51n through § 31-51s) is Connecticut's state-level plant closing, relocation, and mass layoff notification law. It applies to employers with 100 or more employees and requires 60 days advance written notice before a covered action, matching the federal WARN threshold and notice period.

What sets Connecticut apart is its explicit relocation trigger. Federal WARN reaches relocations only indirectly, by treating a move as a kind of plant closing. Connecticut names relocation as its own category: moving all or substantially all operations to a point 50 or more miles away, affecting 50 or more employees, requires notice. That distinction matters most for employers who are moving rather than shutting down.

Both laws usually apply together

Because Connecticut and federal WARN share the same 100-employee threshold and 60-day notice period, employers covered by one are almost always covered by the other. You must comply with whichever law is more stringent on a given requirement. The practical divergence is the relocation trigger: a 50-mile move that retains all employees can sit entirely outside federal WARN while squarely inside CT WARN.

Does CT WARN apply to your action?

Work through these questions in order. If you answer yes to each, CT WARN notice is required.

1

Do you have 100 or more employees?

The Connecticut Business Closing Act applies to employers with 100 or more employees, the same threshold as federal WARN. Count employees company-wide, not just at the affected Connecticut site.

Yes: Continue to step 2
No: CT WARN does not apply.
2

Is the action a plant closing, a 50+ mile relocation, or a mass layoff?

Connecticut covers three distinct triggers: a permanent shutdown of a business, a relocation of all or substantially all operations to a point 50 or more miles away, or a mass layoff. The relocation trigger is the key difference from federal WARN.

Yes: Continue to step 3
No: CT WARN does not apply to this action.
3

Does the action meet the employee-count threshold within 60 days?

A plant closing or relocation must affect 50 or more employees. A mass layoff must affect 500 or more employees, OR 50 or more employees who represent at least 33% of the full-time workforce. All counts are measured within a 60-day period.

Yes: Continue to step 4
No: CT WARN does not apply unless another trigger is met.
4

Does an exception apply?

Three exceptions exist, the same as federal WARN: faltering company (plant closings and relocations only), unforeseeable business circumstances, and natural disaster. If one applies, reduced notice may be permissible. You must still give as much notice as practicable and explain the exception in the notice itself.

Yes: Reduced notice may be permissible. See the Exceptions section.
No: Full 60-day notice is required.

Thresholds and triggers

The Connecticut Business Closing Act uses three trigger categories: plant closing, business relocation, and mass layoff. All three require 60 days notice. The difference is what kind of action is happening and how many employees are affected.

What counts as an "employment loss"

The thresholds below count only employees who experience an "employment loss." Under WARN, employment loss means any of the following:

  • Termination, other than a discharge for cause, voluntary departure, or retirement
  • A layoff exceeding 6 months
  • A reduction in hours of more than 50% during each month of any 6-month period

For relocations, employees offered the option to move with the operation may still count toward the threshold. Connecticut's relocation trigger is not avoided simply by extending transfer offers.

Employer coverage threshold

CT WARN applies to employers with 100 or more employees, matching federal WARN. Count employees company-wide, not just in Connecticut.

Count toward 100

  • Full-time employees (20+ hours/week)
  • Employees on paid leave
  • Employees on temporary layoff with recall rights

Do not count

  • Part-time employees (under 20 hours/week)
  • Employees with fewer than 6 months tenure
  • Independent contractors

Plant closing and relocation trigger

A plant closing is a permanent shutdown of a business. A relocation is a move of all or substantially all operations to a point 50 or more miles away. Either action triggers notice if it affects, within a 60-day period:

50 or more employees

The relocation trigger is the key distinction

Federal WARN reaches relocations only as part of a plant closing. Connecticut names relocation as its own trigger. A company moving its Hartford headquarters to Boston, more than 50 miles, must give 60-day notice even if it offers every employee the chance to follow. The "all or substantially all operations" language has been interpreted broadly by Connecticut courts.

Mass layoff trigger

A mass layoff (not a plant closing or relocation) requires notice if either of these thresholds is met within a 60-day period:

Option A

50+ employees

who represent at least 33% of the full-time workforce

Option B

500+ employees

regardless of what percentage of the workforce they represent

Mirrors federal WARN

Connecticut's mass layoff thresholds match federal WARN: 500 employees, or 50 employees representing at least one-third of the workforce. The federal and state mass layoff analysis will usually reach the same answer.

60-day aggregation rule

Connecticut measures employment losses within a 60-day period. Staggered separations across a relocation or closing are combined and treated as a single event if they fall within that window. An employer cannot avoid the 50-employee relocation threshold, or the mass layoff thresholds, by splitting an action into smaller waves spread across the relocation or closing period. Connecticut courts scrutinize the timing and intent.

Exceptions to the 60-day requirement

The Connecticut Business Closing Act mirrors the three federal WARN exceptions. All three reduce the required notice period. They do not eliminate it. The employer must still give as much notice as practicable and explain the exception in the notice itself.

Faltering company

Plant closings and relocations only

The employer was actively seeking capital or business at the time 60-day notice would have been required, and reasonably believed in good faith that giving notice would have precluded obtaining that capital or business.

Limits

  • Applies only to plant closings and relocations, not mass layoffs.
  • The employer must have been actively seeking capital, not merely hoping for it.
  • The notice must explain that the faltering company exception is being invoked.

Unforeseeable business circumstances

All triggers

The closing, relocation, or layoff was caused by business circumstances that were not reasonably foreseeable at the time 60-day notice would have been required, such as a sudden, dramatic, and unexpected action by a major customer.

Limits

  • The circumstances must be sudden and unexpected, not merely a worsening trend the employer was aware of.
  • Loss of a major customer is a classic example; a predictable revenue decline is not.
  • Notice must be given as soon as practicable and must describe the circumstances.

Natural disaster

All triggers

The closing, relocation, or layoff was a direct result of a natural disaster: flood, earthquake, drought, storm, tidal wave, or similar natural disaster.

Limits

  • The action must be a direct result of the disaster, not downstream economic effects.
  • Even with this exception, the employer must provide notice as soon as practicable.

Notice requirements

WARN notice must be written. Connecticut requires the same three recipients as federal WARN, with state agency notice going to the Connecticut Department of Labor (CTDOL).

Who must receive notice

  • Affected employees

    Each employee who will experience an employment loss. If the employee is represented by a union, notice goes to the chief elected officer of the union local.

  • Connecticut Department of Labor (CTDOL)

    The Connecticut Department of Labor, the state dislocated worker unit. Notice must include the layoff details specified by the statute.

  • Chief elected local official

    The mayor, first selectman, or equivalent of the unit of local government where the layoff, closing, or relocation will occur.

Required content of the notice

  • Name and address of the employment site where the action will occur

  • Name and telephone number of the company official to contact for further information

  • Statement of whether the planned action is a closing, a relocation, or a mass layoff, and whether it is permanent or temporary

  • Expected date of the first separation and the anticipated schedule of separations

  • Job titles of positions to be affected and names of workers holding those positions

  • For a relocation, the new location and whether affected employees are offered the option to transfer

Notice must be specific to be valid

A general announcement that a move or layoff is coming does not satisfy WARN. The notice must identify the affected employees by position, state the expected date of the first separation, and specify the site. For a relocation, an offer to transfer does not replace the written notice obligation. Broad internal communications or press releases do not substitute for written WARN notice delivered to each required recipient.

Connecticut WARN vs. federal WARN

CT WARN shares most of its structure with federal WARN: same employer threshold, notice period, and mass layoff triggers. The one major divergence is the explicit relocation trigger. Rows highlighted in green are where Connecticut differs.

CT WARN differences highlighted in green. The explicit relocation trigger is the practical reason to run a separate Connecticut analysis: a 50-mile move that retains all employees can fall outside federal WARN yet inside CT WARN.

Penalties for violation

Connecticut does not require mandatory severance. The penalty structure mirrors federal WARN: back pay and benefits for the violation period, plus a civil penalty.

Per-employee liability

Back pay at the employee's regular rate, plus the value of benefits (including medical expenses that would have been covered), for each day of the violation, up to 60 days total per employee.

Civil penalty

Up to $500 per day for each day of violation. This penalty can be offset if the employer makes voluntary payments to affected employees during the violation period.

How liability is calculated

If an employer gives 30 days notice when 60 days was required, the violation period is 30 days. For an employee earning $1,500/week with $500/month in benefits:

Back pay: 30 days × ($1,500 / 5 days) = $9,000

Benefits: 30 days × ($500 / 30 days) = $500

Total per employee: $9,500

Multiply by the number of affected employees. For a 100-person action with 30 days of missing notice, total back pay exposure can exceed $900,000 before civil penalties.

Common mistakes

Treating a relocation as outside WARN because no one is losing their job

The explicit relocation trigger catches employers who are moving offices rather than closing. A company relocating its HQ from Hartford to Boston, more than 50 miles, must give 60-day notice even if it offers every employee the option to move. The intent to retain employees does not avoid the obligation.

Underestimating the 50-mile relocation threshold

Fifty miles is shorter than many employers expect. A move within the same metro region, or just across a state line, can exceed 50 miles and trigger CT WARN. Measure the distance before assuming a relocation is exempt.

Relying only on a federal WARN analysis for a Connecticut move

Federal WARN reaches relocations only indirectly, as part of a plant closing. A relocation that retains all employees may sit entirely outside federal WARN while squarely inside CT WARN. Always run a separate Connecticut analysis for any move of operations.

Forgetting to notify the Connecticut Department of Labor

Employers frequently remember to notify employees and the local government but miss the state agency notice. All three recipients are required. CTDOL notice must include the layoff details specified by the statute.

Ignoring the 60-day aggregation rule when phasing an action

Splitting a relocation or closing into smaller waves across the relocation period does not avoid WARN. Employment losses within a 60-day window are aggregated. Counsel should review any multi-phase action before the first notice goes out.

Reading "all or substantially all operations" too narrowly

Connecticut courts have interpreted the "all or substantially all operations" relocation language broadly. Moving the bulk of a business operation can qualify even if a small remnant stays behind. Do not assume a partial-retention move is automatically exempt.

Frequently asked questions

What is the Connecticut Business Closing Act?

The Connecticut Business Closing Act (Conn. Gen. Stat. § 31-51n through § 31-51s) is Connecticut's mini-WARN law. It requires employers with 100 or more employees to provide 60 days advance written notice before a plant closing, a business relocation of all or substantially all operations to a point 50 or more miles away affecting 50 or more employees, or a qualifying mass layoff, all measured within a 60-day period.

How does Connecticut WARN differ from federal WARN?

The biggest difference is that Connecticut explicitly treats a business relocation, moving all or substantially all operations 50 or more miles away, as its own separate trigger category. Federal WARN covers relocations only indirectly, as part of the plant closing definition. Connecticut's explicit relocation trigger means an employer moving operations 50+ miles, even one that intends to retain every employee who can follow, must analyze CT WARN separately. The employer threshold (100), notice period (60 days), and the three exceptions match federal WARN.

Does a business relocation trigger CT WARN notice?

Yes. Connecticut explicitly covers the relocation of all or substantially all of a business operation to a point 50 or more miles away, affecting 50 or more employees within a 60-day period. This applies even if the employer intends to offer every affected employee the option to move with the operation. A company relocating its headquarters from Hartford to Boston, for example, must give 60-day notice even if it plans to let all employees follow.

What is the penalty for violating the Connecticut Business Closing Act?

An employer that violates the Connecticut Business Closing Act is liable to each affected employee for back pay and the cost of benefits for each day of the violation period, up to 60 days. The employer is also subject to a civil penalty of up to $500 per day of violation, the same structure as federal WARN. Voluntary payments made to employees during the violation period can reduce liability.

Does Connecticut require mandatory severance?

No. Unlike New Jersey, Connecticut does not require mandatory severance under the Business Closing Act. Violations of the notice requirement trigger back pay and benefits liability for up to 60 days, plus civil penalties, but there is no separate statutory severance entitlement. Connecticut does have a separate continuation-of-benefits obligation for certain plant closings under § 31-51o, but that is distinct from a severance mandate.

Who must receive WARN notice in Connecticut?

Under the Connecticut Business Closing Act, the employer must provide written notice to: (1) each affected employee or their union representative; (2) the Connecticut Department of Labor (CTDOL); and (3) the chief elected official of the unit of local government where the layoff or closing occurs. All three recipients are required, and the notice must include the layoff details specified by the statute.
