Promissory notes and work tools in the employment file

In today's operational dynamics, assigning work tools—such as laptops, smartphones, vehicles, or specialized machinery—is essential for performing job functions. However, the lack of adequate documentation regarding the delivery, custody, and return of these assets often generates significant losses when the employment relationship ends unexpectedly.

The legal boundary between work tools and liability

According to the Federal Labor Law, the employer is obligated to provide the tools and instruments necessary for the performance of the work. At the same time, the worker is obligated to use them with due care and return them when the relationship ends. To formalize this responsibility, many companies use acknowledgment of receipt letters or complementary instruments.

A recurring mistake is using generic printed templates that get misplaced or are poorly signed. If, at the time of dismissal or resignation, the former employee denies having received the equipment or does not recognize their signature on the receipt, the company will have a hard time recovering the asset or deducting its cost in accordance with the law.

Secure digitalization of receipts

Sora allows you to manage all work tool control from the cloud:

1. Link the receipt to the employee: The delivery document specifies serial numbers, brand, and conditions of the asset.

2. Robust authentication: The employee signs the acknowledgment of receipt letter using Cryptographic Signature with Facial Biometrics.

3. Receipt and inalterability: The signed file is encrypted with zero-knowledge ed25519 technology and stored in the worker's file.

4. Official validation: The identity of the signer is validated in real time against the RENAPO servers.

With this infrastructure, the company has irrefutable proof of the receipt of the asset, ensuring that administrative labor compliance supports the protection of corporate property at all times.
