Essential formal precautions for companies to take against labor risks in outsourcing.

November 3, 2025

The topic of outsourcing has once again gained prominence in the legal field, with recent analyses reinforcing the importance of observing formalities when hiring service providers. The central concern is to prevent outsourcing from being distorted and resulting in the recognition of a direct employment relationship between the contracting company and the outsourced workers. For managers and HR directors, this warning is crucial, as formal errors can lead to significant labor lawsuits and compromise the organization's legal security.

In practice, the greatest risk lies not only in the content of the contract, but in how outsourcing is operationalized on a daily basis. Labor courts have repeatedly stated that establishing an employment relationship depends on the presence of elements such as subordination, personal service, and regularity. This means that, even with a well-drafted contract, if the outsourced worker is treated as a direct employee of the contracting company, the company can be held liable.

Furthermore, simple formal precautions—such as ensuring that outsourced workers wear uniforms and badges from the service provider, maintaining communication always through the contracted company and not directly with the outsourced workers, and clearly defining the outsourced activities—are significantly important. These details act as legal barriers against interpretations that there is direct interference by the contracting company in workforce management.

Another point of attention is the monitoring of contracts. Although it is the service provider's obligation to fulfill labor obligations, the contracting party must ensure a minimum level of documentary oversight, such as requiring proof of payment of social security contributions. Neglect in this aspect can lead to joint or subsidiary liability, increasing financial risk.

To reduce risks, companies should adopt clear governance over outsourcing. This involves training managers and supervisors so that they do not confuse their roles with the direct management of third parties, as well as establishing internal policies that define the responsibilities of each party. It is also advisable to maintain organized records of all documentation proving the fulfillment of obligations by the contracted company.

A practical example: if a third-party security company provides services at its facilities, it is the client's responsibility to periodically request proof of payment of FGTS (Brazilian severance pay fund) and INSS (Brazilian social security) contributions, file these documents, and restrict operational communication to the contractor's manager. This preventative approach protects the company in the event of an audit or legal action.
