The Workers' Food Program (WFP) aims to improve the nutritional status of workers. This study evaluated the knowledge of WFP's administrative and technical managers promoting healthy diet and health, and the interface of this issue with the program. The study comprised eight companies registered in WFP, located in the city of Chapeco-SC, Brazil, with over 150 employees, who had dining hall and nutritionists. We applied a questionnaire, and the recordings were transcribed and analyzed using the technique of content analysis. On why the company has been registered in WFP, between the key expressions, administrative managers refer to the tax benefit granted to the company. Technical managers most frequently emphasized the benefit to the workers. Asked what WFP is, the administrative managers commented most frequently about the employee's welfare. On the same subject, the technical managers cited more features about the program. It was found that most of the technical and administrative managers responsible for WFP had vague knowledge about the program. In the speech, it was observed that many managers leave more explicit fiscal objectives for the company, not highlighting the main objectives for employees; however, the technical managers demonstrated greater clarity on the role of WFP with the health worker than administrative managers.
