Brazilian digital bank Nubank dismissed two employees for just cause after detecting an alleged plan to sabotage its internal systems, according to an internal communication seen by O Globo.

The dismissals, announced on Monday, follow a series of terminations last week that coincided with employee protests over the company’s move from remote to hybrid work.

Chief Technology Officer Eric Young told staff that “through our regular Information Security operations, we detected that two employees were planning to sabotage internal systems. We acted quickly to prevent these employees from taking any concrete steps in their plan, utilising our robust defences against any type of threat. The employees were immediately terminated and reported to the authorities.”

Nubank confirmed that evidence was handed to the police and that the São Paulo Bank Workers’ Union had been notified. The bank did not comment publicly. The latest dismissals bring the total to 14 since last week.

The union is demanding clarification after 12 workers were fired following an online meeting about new attendance rules. Nubank said the terminations were linked to “inappropriate behaviour” during that meeting, not opposition to the hybrid model.

CEO David Vélez addressed criticism on LinkedIn, writing to a former employee: “You have very little information, my friend. You have no idea about the type of language and behaviour these people use. They confused a corporate channel with a social network or a stadium grandstand.”
