This paper aims to analyze the legal discourse from a rhetorical perspective. For this reason, rhetoric was used as a research method. Regarding the theoretical framework, based on legal hermeneutics and the speaker’s ethica, the contributions from legal scholars like Tercio Sampaio Ferraz Junior and João Maurício Adeodato were elected. Those jurists recognize the existence of rhetoric in law and conceptualize the theme, classifying it didactically as a linguistic phenomenon. The purpose of this dissertation is to examine the following corpus: eight labor court decisions, four in favor of the employee and four in favor of the company, involving venire contra factum proprium (the prohibition of inconsistent behavior) and the loss of chance doctrine. The rhetorical tripod (ethos-pathos-logos) and the speaker's virtues (arete-eunoia-phronesis) were considered as an analytical tool. Although it is not intended to exhaust the subject, this is an unprecedented thesis, which proposes adopting a heterogeneous and non-reified view of labor decisions, consolidating the speaker’s position and the linguistic elements introduced in the discourse involving this area of law. The study ultimately contributes to a reflection on the legal textual genre and its outcomes, all of which are transversed by persuasion to the detriment of normative constraints and the contradictory behavior of the parties involved in the legal demands brought up for debate
