Wisconsin Drug Testing Laws for Employers

The Total Bar

Wis. Stat. 102.58(2) is one of the most employer-favorable workers' compensation provisions in the country. Where an employee violates the employer's policy concerning employee drug or alcohol use, is injured, and that violation is causal to the injury, no compensation or death benefits are payable — to the employee or to a dependent. A narrow slice survives: incidental compensation under 102.42(1) to (8) and drug treatment under 102.425.

That is a complete denial of indemnity and death benefits, not the fifteen or fifty percent reductions most states use. And its trigger is violation of the employer's own policy rather than a statutory intoxication standard with a numeric threshold.

Which produces an unusual conclusion. The statute supplies no thresholds, no testing procedure and no presumption, so a hearing turns entirely on three things you control: what your Wisconsin policy actually prohibits, which cutoff levels it adopts, and whether you have enforced it consistently. In most states a better policy is good hygiene. In Wisconsin it converts directly into claim outcomes.

Where there is no policy concerning drug or alcohol use, there is nothing for the employee to violate and the bar simply collapses.

A narrower fallback sits in Wis. Stat. 102.58(1): a fifteen percent reduction, capped at $15,000 total, where injury is caused by failure to use statutorily required safety devices that are adequately maintained and reasonably enforced, or by failure to obey any reasonable rule adopted and reasonably enforced by the employer for the employee's safety and of which the employee has notice. Reasonableness, consistent enforcement and proof of notice are all part of the employer's case there.

One honest caveat. Published annotations to 102.58 state that the burden of proof is on the employer to establish both intoxication and causation, and that intoxication decreases rather than defeats a claim. Those propositions come from case law rather than the statutory text, and the second predates the current subsection (2). How the two fit together now is a question for counsel rather than one we can answer from the code.

Wisconsin Asks You to Report Failed Applicant Tests

This is unusual enough to be worth building a process around. Wis. Stat. 108.133(4)(a) permits an employing unit to voluntarily submit to the Department of Workforce Development the results of a test for unlawful use of controlled substances conducted as a condition of an offer of employment, or to notify the department that an individual declined to submit to such a test, along with identifying information.

Wis. Stat. 108.04(8)(b) then creates a rebuttable presumption that the employee failed, without good cause, to accept suitable work when offered — where the department determines from that report that the employing unit required the test as a condition of an offer and withdrew the conditional offer after the individual either declined to test or tested positive without evidence of a valid prescription.

Two embedded conditions decide whether the benefit is available at all:

1. The test must have been required as a condition of an offer of employment.
2. The employer must actually have withdrawn the conditional offer.

A program that screens before making an offer, or that simply goes quiet on a candidate after a positive, never produces the reportable event the statute describes. The test must also have been conducted and certified in a manner approved by the department, with implementing rules at Wis. Admin. Code ch. DWD 131. Good-faith reports carry statutory immunity.

The Exposure Is Alcohol and Tobacco, Not Cannabis

Wisconsin's Fair Employment Act lists, among its prohibited bases of discrimination, "use or nonuse of lawful products off the employer's premises during nonworking hours" — alongside age, race, creed, color, disability, marital status, sex, national origin, ancestry, arrest and conviction record and military service.

Cannabis is not a lawful product here. Wis. Stat. 961.14(4)(t) places tetrahydrocannabinols in Schedule I, with narrow exclusions for a cannabidiol product dispensed or possessed as the statute allows, THC in fiber, oil or cake from stalks or seeds, THC in hemp, and certain finished-dosage drug products. The cannabidiol allowance is expressly non-psychoactive and carries no employment protection. So a confirmed cannabis positive does not implicate the lawful-products basis at all.

Alcohol and nicotine do. Any consequence your program attaches to off-duty use of those has to fit one of the exceptions in Wis. Stat. 111.35(2): the use impairs the individual's ability to undertake their job-related responsibilities adequately; creates a conflict of interest or its appearance; conflicts with a bona fide occupational qualification reasonably related to those responsibilities; constitutes a violation of Wis. Stat. 254.92(2); or conflicts with any federal or state statute, rule or regulation. That last paragraph is what covers DOT-regulated and other federally mandated testing.

Two questions the statutes do not answer, and which belong with counsel: whether a claim framed as disability discrimination under Wis. Stat. 111.34 rather than as lawful-product discrimination changes the analysis, and whether any protection attaches where lawful use of a CBD product produces a confirmed THC positive.

What To Do About It

Wisconsin rewards a well-drafted policy more directly than almost any other state, so the work here is drafting rather than compliance:

• State the prohibited conduct precisely, including that a positive result or a refusal is itself a violation, since 102.58(2) keys off violation of the policy.
• Name the cutoff levels in the policy, because the statute supplies none and a hearing will ask what standard the employee violated.
• Document enforcement consistently. An inconsistently applied policy is a weaker foundation for a total bar than a modest one applied evenly.
• Make pre-employment testing post-offer, and withdraw the offer explicitly when acting on a positive, so the unemployment reporting route stays open.
• Check off-duty alcohol and tobacco consequences against the 111.35(2) exceptions.

Where This Lands

Wisconsin's employment base runs through food and dairy processing, machinery and metal fabrication, paper and forest products, healthcare, transportation and warehousing, agriculture, and construction. Processing and fabrication employers carry the injury profile where a total workers' compensation bar is worth real money — and they are also the employers most likely to have a policy written years ago that has never been read against 102.58(2).
