Essential Legal Distinctions
- Primacy of Reality Prevails: Labor judges evaluate actual facts rather than artificial tax classifications.
- WhatsApp is Fully Admissible: Supervisor instructions and audio messages serve as valid electronic proof.
- Article 23 Statutory Presumption: Proving service delivery legally presumes an employment contract.
1. Evidentiary Standards for Off-the-Books Employment
Under the primacy of reality doctrine (Article 14 LCT), Argentine labor courts prioritize actual daily working conditions over artificial contract forms.
Employees proving off-the-books or underreported employment rely on five primary evidentiary channels:
- Witness Testimony: Coworkers, clients, or security personnel confirming work shifts, supervisory orders, and physical presence.
- Digital Evidence (WhatsApp & Emails): Work schedules, instructions, and performance feedback from supervisors. Court precedents in Buenos Aires grant full evidentiary weight to digital communications.
- Bank & Electronic Transfers: Periodic payment transfers from company accounts, Mercado Pago, or management personal accounts.
- Access Logs & Security Records: Building entrance logs and biometric records.
- Statutory Presumption (Article 23 LCT): Proving actual service performance creates a statutory presumption of an employment relationship.
2. Securing Evidence Prior to Dispatching Telegrams
Before issuing demand notices, employees should back up all WhatsApp chat logs, retain transfer receipts, and secure full contact information for at least two reliable trial witnesses.
