Is the employer always liable for a workplace accident?

A workplace accident follows a largely predictable path to litigation. The company files the CAT (the mandatory work accident report), the employee takes social security leave and, months later, a labor claim is filed, typically combining moral and material damages, substitute compensation for the accident-related period of job protection, severance amounts and constructive termination of the contract. In the case file, the occurrence of the accident is rarely disputed; the central issue is whether the company breached a duty of prevention. Contrary to what many business owners assume, the answer to that question can be no.

Employer liability requires fault

The Brazilian Constitution grants the injured worker compensation only where the employer acted with intent or fault (art. 7, XXVIII). In labor practice, fault has a precise meaning: failure to comply with occupational health and safety rules, or failure to instruct employees on the risks of the activity, duties that art. 157 of the CLT (the Brazilian labor code) assigns to the employer. A company that has met those duties is not liable for an accident caused by the worker's own negligence.

This is the doctrine of the victim's exclusive fault. Where the decisive cause of the accident was the conduct of an employee who disregarded documented safety instructions, the causal link is broken and no duty to compensate arises (art. 186 of the Civil Code). For activities involving heightened risk the courts apply strict liability (art. 927, sole paragraph, of the Civil Code), but even then the victim's exclusive fault excludes liability. The relevant distinction is between exclusive and concurrent fault: if the company also breached a duty of prevention, the worker's negligence merely reduces the amount of the award.

The evidence must carry a date

Asserting in the defense that the worker acted on his own initiative is not sufficient. Courts recognize exclusive fault where the company proves that it performed its own duties, and that proof is documentary: a safety service order under regulatory standard NR-1, an acknowledgment of the internal safety rules signed at hiring, PPE delivery records and training attendance sheets.

The date of those documents matters as much as their content. At the hearing, it is common for the worker to acknowledge the signature while claiming the document was signed shortly before the lawsuit. That allegation alone does not defeat the document, because the party asserting that the date is false bears the burden of proving it (art. 818, I, of the CLT; art. 373, I, of the Code of Civil Procedure). An acknowledgment executed at hiring and kept on file since then withstands that challenge; a document prepared hastily after the accident usually does not.

At the evidentiary stage, the court weighs the worker's testimony against the physical dynamics of the accident. A version inconsistent with the position of the equipment or the movement of the vehicles undermines the complaint, and in warehouse and logistics operations, where vehicle maneuvers and blind spots concentrate the risk, that comparison is often decisive.

Conduct after the accident also becomes evidence

A significant share of adverse judgments originates in the period after the accident, when the company fails to follow the required steps. Those steps are well established: filing the CAT by the next business day (art. 22 of Law 8,213/91), paying the first fifteen days of leave, observing the restrictions in the return-to-work medical certificate and, where necessary, reassigning the employee to duties compatible with his condition.

When that sequence is followed, two claims that accompany most accident lawsuits lose their basis. Substitute compensation for the accident-related period of job protection (art. 118 of Law 8,213/91) presupposes dismissal; with the contract in force and the medical restrictions observed, there is nothing to compensate. Constructive termination, in turn, requires a serious breach by the employer, which is difficult to establish when the employee continues to work in duties adjusted to his health.

The documentation must exist beforehand

The risk inventory of the PGR (the mandatory risk management program), the service orders, the dated training records and the written procedures for vehicle maneuvering areas form the material the company's counsel will rely on in court, and none of it can be produced after service of process. Companies that treat this documentation as part of routine management spend the hearing discussing the worker's conduct; those that treat it as a formality end up discussing their own omission.

Periodic review of those documents by professionals familiar with accident litigation serves a direct purpose: missing documents and inconsistent dates come to light while there is still time to correct them.
