Labor Court and Consumer Actions Show Worrying Growth of Black Friday Litigations, Which Already Exceed R$ 2 Billion.
What should only boost sales has become, according to a study by Predictus, one of the periods with the highest number of judicial conflicts in the country.
The research shows who are the most affected (consumers and workers), when the litigations occurred (between 2015 and 2025), where they are concentrated (mainly in the Southeast), how these processes arise (due to failures in offers and excessive working hours) and why the situation generates judgments that exceed R$ 2 billion.
Right from the first data, the study reveals that more than 50,000 cases are directly linked to Black Friday, showing that the commercial event, despite being profitable, has also become a major legal problem for companies in various sectors.

Black Friday Litigations Exceed R$ 2 Billion and Expose Hidden Impact on Commerce
Predictus analyzed 50,200 cases involving Black Friday between November 2015 and September 2025.
Of this total, the cost of judgments exceeds R$ 2 billion, considering consumer actions and claims filed in the Labor Court.
Thus, although the date is seen as a sales driver, the numbers indicate a reverse effect that financially impacts commerce and increases legal insecurity in various operations.
Consumers Are the Most Active in Common Justice During Black Friday
The analysis identified 6,032 cases filed by consumers, most of which are related to breaches of offers and serious failures in store service.
The main reasons for the actions include:
Breach of Offers (638 cases);
Price Errors;
Unilateral Cancellations;
Products Not Delivered.
These problems, on the other hand, reveal that there is still a structural difficulty for companies to deal with the increased demand during the event.
Southeast Accounts for More Than 61% of Consumer Actions
The states of Rio de Janeiro, São Paulo, and Minas Gerais account for 61.39% of all consumer actions involving Black Friday.
Commerce, especially large retail, dominates the list of the most sued segments.
Among the leaders in cases are:
1-Appliance and Audio-Video Equipment Trade – 571 cases (9.47%);
2-Department Stores – 528 cases (8.75%);
3-Supermarkets – 411 cases (6.81%).
Together, these sectors account for 25.03% of consumer complaints.
Labor Court Registers 44 Thousand Actions and Points to Excessive Pressure in the Sector
The study also identified a significant volume of litigations in the Labor Court, involving commercial employees working during Black Friday.
A total of 44,174 cases were analyzed over the last 10 years.
Of the total, 37,461 actions expressly mention the term “Black Friday”, while the remainder is directly related to the promotion period.
The main reason for complaints is the non-payment of overtime, responsible for 25,600 cases.
The average is 24.96 hours of overtime per case, revealing almost an entire week of unpaid work.
Appliance Trade Also Leads Labor Cases
Just as with consumers, the biggest targets of labor actions are:
Appliance and Audio-Video Trade – 3,323 cases;
Department Stores – 3,319 cases;
Trade of Other Unspecified Products – 3,180 cases.
These three segments together account for 22.23% of labor disputes.
In addition, salespeople and cashiers lead the complaints, with more than 14,000 cases, driven by the intense pressure for results during the event.
Southeast Also Dominates the Labor Court
São Paulo, Minas Gerais, and Rio de Janeiro account for almost 60% of all labor actions, reinforcing that the legal impact of Black Friday is significantly greater in the most populous and economically active region of the country.
Financial Cost: Labor Court Is Responsible for the Largest Share
The numbers show a contrast between the two spheres:
Common Court: R$ 8.4 million in judgments (average of R$ 1,400 per case);
Labor Court: R$ 1.2 billion in judgments (average of R$ 27,433 per case).
These amounts explain why the event, despite being crucial for sales, generates enormous legal concerns for companies in commerce.
ブラックフライデーを誰も”ブラフラ”と略していない異常さに気づくべきである。つまりsnsに氾濫するブラックフライデーはすべて日本語理解していない外国AIもしくはそもそも単語自体が全く認知されていないので略せない。つまりブラックフライデー浸透してきたというのは明らかなフェイク。ちなみにブラックフライデーのダンピングによるGDP押し下げ効果は約0.1%から0.3%ぐらい。分かりやすい大資本による消費者誘導であり騙される人は愚か。
