What the sources say. Each statement ends with a note that carries its quote.

The role

Mercado Libre dismissed 119 employees in Latin America, 32 of them in Argentina.1 The cuts fell mainly on UX writers, the role that designs content and user journeys inside the platforms.2

Workers from different countries were called to mass meetings on Zoom, where a Human Resources statement was read in Spanish and Portuguese.3 After the call they lost immediate access to their accounts and work tools.4 Lola Rodríguez, one of the dismissed workers, said the company told them it was seeking generalist roles.5

During 2025, UX workers were assigned to train the artificial intelligence model as part of their job.6 Former employees said they spent much of their work training automated systems that now answer customers and sellers, including through WhatsApp.7 Professionals who stayed on the team would have access to new AI tools, and designers were expected to take on part of the tasks previously done by UX writers.8

The change

Many of those dismissed said the process was directly linked to artificial intelligence.9

What happened next

By 16 January 2026, users and sellers were reporting more interactions handled by automated agents, especially through channels such as WhatsApp.10 Some said simple problems were resolved only after insisting until they reached a human operator.11

A lawyer represented a former Mercado Libre employee in a case seeking reinstatement to the company’s staff.12 The case was rejected at the 2nd Labour Court of Osasco and accepted on appeal.13 The judge understood that the episode corresponded to a mass dismissal, without notification to the legal unions, which would invalidate the dismissal.14 The judge ordered Mercado Libre to re-admit the worker.15

Open questions

  • Did Mercado Libre appeal the reinstatement order, and is the worker back at work?
  • How is the app text that remaining designers now produce with the AI tools being received by users?
  • Have users and sellers reported further trouble reaching a human operator?
  • Has Mercado Libre hired UX writers or content staff again?

The doorman reading

Analysis. This is the site’s reading of what the sources describe, not something they say.

  • Judgment

    Spotting the case the script does not cover, and escalating it

    Some accounts said simple problems were resolved only after insisting until the person reached a human operator.S4

  • Signal

    A person's presence tells customers they matter

    The platform now faces rigid and less nuanced responses after dropping the people who made interactions more empathetic.S4

  • Slack

    Spare capacity that only shows in a crisis

    The union said workers who stayed were told they would also take on the Content area's responsibilities, accumulating functions.S6
