Wisconsin Business Closing Law: 60 days notice for smaller employers

Wisconsin's Business Closing Law, often referred to as a "mini-WARN" Act, mandates employers with 50 or more employees to provide 60 days' advance notice before a business closing or mass layoff. This state-specific requirement applies to situations that might fall below the federal WARN Act's 100-employee threshold, expanding protections for Wisconsin workers. Non-compliance can lead to civil actions for back wages and benefits.

What those rules do as a Wisconsin shift is created.

The Wisconsin Business Closing Law adds a layer of protection for employees beyond the federal WARN Act. Teambridge integrates these thresholds to ensure compliance whether you are a smaller employer in Wisconsin or operating across multiple states with varying mini-WARN laws.

Identify Employer Size

Teambridge continuously monitors your employee count in Wisconsin. If your workforce reaches 50 or more employees within the state, the Wisconsin Business Closing Law's notice requirements are activated.

Flag Layoff/Closing Events

When a planned business closing or mass layoff event is initiated in Teambridge, the system cross-references the employee count and the nature of the event against Wisconsin's specific thresholds (e.g., 25 employees affected in a 30-day period).

Automate Notice Reminders

If a closing or layoff event triggers the Wisconsin Business Closing Law, Teambridge automatically generates reminders and prompts for the required 60-day advance notice to affected employees, the Department of Workforce Development (DWD), and local officials, mitigating non-compliance risks.

The rule, plainly stated

Wisconsin's Mini-WARN Act requires 60 days' notice for closings or mass layoffs affecting 25+ employees at businesses with 50+ staff.

The Wisconsin Business Closing and Mass Layoff Law (Wis. Stat. § 109.07) provides greater worker protection than the federal WARN Act by covering smaller employers and lower thresholds for triggering events. It applies to employers with 50 or more employees operating within the state.

Wis. Stat. § 109.07: Business closings and mass layoffs.

(1) Definitions. In this section:

(a) "Business closing" means the permanent or temporary shutdown of an employment site or of one or more facilities or operating units within a single employment site, if the shutdown results in the termination of employment, other than a temporary layoff, of 25 or more employees as a result of the shutdown.

(b) "Employer" means any person who employs 50 or more employees in this state.

(c) "Mass layoff" means a reduction in force which is not the result of a business closing and which results in the termination of employment, other than a temporary layoff, of at least 25% of the employees or 25 employees, whichever is greater, within any single employment site during any 30-day period.

(2) Notice requirements. An employer shall provide written notice to the department, any affected employee, and the collective bargaining representative of any affected employee at least 60 days prior to the date of a business closing or mass layoff.

Covered Employers and Events

An employer is covered by the Wisconsin Business Closing Law if it employs 50 or more employees in the state. A "business closing" is defined as a shutdown resulting in the termination of 25 or more employees. A "mass layoff" occurs when there's a reduction in force, not due to a business closing, that results in the termination of at least 25% of the employees or 25 employees, whichever is greater, within a single employment site during any 30-day period.

Notice and Penalties

When a covered event occurs, the employer must provide written notice at least 60 days in advance to the Wisconsin Department of Workforce Development (DWD), any affected employees, and any collective bargaining representatives. Failure to comply can result in liability for back pay and benefits for each day of violation, up to 60 days, to each affected employee. The DWD may also impose civil forfeitures for violations.
