Wisconsin Paid Sick Leave Laws: Your Entitlements

The Family and Medical Leave Act (FMLA), 42 U.S.C. § 2601, requires covered employers with 50 or more employees to provide 12 weeks of unpaid, job-protected leave per 12-month period for qualifying reasons including the employee's own serious health condition, care for a family member with a serious health condition, birth or adoption of a child, or military family leave. The FMLA is administered by the U.S. Department of Labor (DOL). Employees eligible for FMLA protection must have worked for the covered employer for at least 12 months and have worked at least 1,250 hours in the past 12 months. While FMLA provides unpaid leave protections, it does not require paid sick leave. The act applies to private employers, state and local governments, and schools. Remedies under FMLA include recovery of lost wages, benefits, and costs (including litigation costs and reasonable attorney fees), and injunctive relief requiring reinstatement or promotion.

Federal law also allows employees to use accrued paid time off (PTO) during FMLA leave if permitted under employer policy. Some states and cities have filled the gap by requiring paid sick leave, recognizing that unpaid leave is unaffordable for many workers.

Wisconsin state law does not mandate paid sick leave for private employers. Wisconsin Statute § 103.10 addresses sick leave regulation but defers to municipal authority. This means Wisconsin employers have no statewide obligation to provide paid sick leave unless they operate in a city or county with a local ordinance requiring it.

However, Wisconsin municipalities have enacted paid sick leave laws more stringent than federal baseline. Milwaukee, Wisconsin's largest city, adopted Municipal Code § 109.01 et seq., which requires employers with 10 or more employees to provide a minimum of 5 paid days off per year for covered employees. This applies to private employers, regardless of federal FMLA coverage. Milwaukee's ordinance is stronger than the federal baseline because it mandates paid leave (not just unpaid protection).

Madison and other Wisconsin cities have also passed local sick leave ordinances with varying thresholds and accrual methods. Employees in those municipalities are entitled to paid sick leave beyond what federal law provides. The state law explicitly permits municipalities to regulate sick leave, meaning local requirements are enforceable.

Covered employers under Milwaukee's ordinance include private employers with 10 or more employees. Excluded are federal contractors subject to the Service Contract Act, which has its own paid leave requirements. Remedies under Wisconsin municipal ordinances include back pay, damages, and attorney fees. Wisconsin does not have a state-wide FMLA equivalent; employees must rely on federal FMLA protections (if applicable) and local municipal ordinances.

Wisconsin state law contains no private sector paid sick leave mandate, so the only exceptions apply to municipal ordinances. Under Milwaukee's ordinance, exempt employees are those in certain professional roles or covered by collective bargaining agreements that provide greater benefits. Employers may satisfy the ordinance by providing combined PTO (paid time off) that meets or exceeds the 5-day threshold.

Small employers with fewer than 10 employees in Milwaukee are exempt from the municipal ordinance. Self-employed individuals and independent contractors are not covered. Employees must have been employed for at least 90 days in Milwaukee before becoming eligible to use paid sick leave, creating a waiting period.

Employers in Wisconsin counties or unincorporated areas without local ordinances have no paid sick leave obligation. Federal FMLA also contains exceptions: employees of employers with fewer than 50 employees are not covered; employees who have not worked 12 months for the same employer are ineligible; employees must have worked 1,250 hours in the preceding 12 months; and employees at worksites with fewer than 75 employees within 75 miles may not be covered.

Union employees in Wisconsin are often covered by collective bargaining agreements that exceed local sick leave requirements. If a CBA provides paid sick leave better than the local ordinance, the CBA prevails. At-will employment is the presumption in Wisconsin, but sick leave ordinances create a contractual obligation once the employer chooses to operate in that municipality. Employers may enforce reasonable notice requirements (typically 30 days advance notice when foreseeable) and may require medical certification for absences exceeding a specified duration.

**Step 1: Document Everything.** Keep records of all instances you requested paid sick leave, the dates, and the employer's response. Save written communications (emails, text messages, letters) that show you are entitled to paid sick leave under your city's ordinance. Retain any employer policy documents, employee handbook, or pay stubs showing sick leave accrual or denial. If you were denied paid sick leave and forced to work while ill, or if your pay was docked when you took entitled sick leave, document the specific dates and amount of pay lost. Record the names and titles of managers or HR personnel involved in denying your leave.

**Step 2: File an Internal Complaint.** Before filing with a government agency, send a written complaint to your employer's HR department or management. Use email (for proof of delivery) and state clearly that you believe your employer violated the municipal paid sick leave ordinance in your city. Specify the dates you requested or took sick leave and were denied, the ordinance violated (e.g., Milwaukee Municipal Code § 109.01), and the remedy you seek (backpay, restoration of wrongfully denied leave, etc.). Request a written response within 10 business days. Keep a copy of this letter. Some employers remedy violations at this stage; if yours does not, you have evidence of notice and good-faith attempt to resolve.

**Step 3: File a Complaint with the Appropriate Agency.** If your employer is in Milwaukee, file a complaint with the City of Milwaukee's Department of Neighborhood Services (DNS) or the office designated to enforce the sick leave ordinance. For other Wisconsin municipalities with paid sick leave ordinances, identify the enforcing agency (often the city's labor department or human resources office). Contact information varies by city; visit your city's official website and search "paid sick leave complaint" or "labor standards enforcement." You will need to provide: (a) your name, address, and contact information; (b) employer name, address, and employer size; (c) dates and details of the sick leave denial or violation; (d) documentation (emails, pay stubs, witness names); (e) the ordinance you believe was violated (with section number); (f) the remedies you seek. File as soon as possible after the violation; municipal ordinances typically have a 1-2 year statute of limitations, but do not delay. If you are covered by federal FMLA and the violation involves FMLA-qualifying leave, you may also file with the U.S. Department of Labor Wage & Hour Division at www.dol.gov/agencies/whd or by calling 1-866-4-USDOL (1-866-487-3652).

**Step 4: Expect the Investigation Process.** Once filed, the municipal agency or DOL will typically contact your employer for a written response within 10-30 days. The agency may request pay records, timekeeping logs, and your employment file. You may be interviewed by an investigator, and your employer will have an opportunity to respond. Most municipal investigations take 30-90 days, though complex cases take longer. If violations are found, the agency will issue a determination and may order the employer to pay back wages (all denied sick leave pay), damages (additional penalties, often 25-100% of back pay), and costs. Some agencies also order the employer to update its policies and provide notice of the violation to all employees.

**Step 5: When to Consult an Attorney and What Type.** If your employer retaliates after you file a complaint (firing, demotion, reduced hours, hostile treatment), or if the municipal agency's determination is unsatisfactory, consult an employment attorney. Contact the Wisconsin State Bar Lawyer Referral Service at 1-800-362-9082 or visit wisbar.org. Seek an attorney who handles wage and hour violations, municipal labor law, and retaliation claims. Many employment lawyers work on contingency (no upfront fee; they take a percentage of your recovery). Your attorney can file a retaliation complaint, demand additional damages, and represent you in settlement negotiations or litigation. If you were fired after reporting the violation, your attorney may also pursue a wrongful termination claim under Wisconsin common law.
