Introduction
Labor Courts have undergone significant transformations regarding the acceptance of digital evidence. In 2025, new decisions from higher courts have consolidated important understandings about how screenshots, WhatsApp messages, and other digital records can be used in labor proceedings.
The current landscape
With the increasing digitalization of work relationships, especially after the pandemic, the amount of digital evidence presented in labor proceedings has grown exponentially. WhatsApp messages, emails, electronic time records, and even social media posts are increasingly common as means of proof.
Requirements for validity
For digital evidence to be accepted in Labor Courts, it must meet some fundamental requirements:
- Authenticity: It is necessary to prove that the digital document has not been altered
- Integrity: The content must be intact, without manipulation
