Rarely do professionals think of the third sector as a career option, with employability and remuneration. Most think of it only as voluntary work. Perhaps this is because its origins, in the 16th century, with the founding of the Santa Casa de Misericórdia de Santos in 1543, the first historical reference to an entity in the sector in Brazil, sustains this character. OBJECTIVES: The general objective is to show society and managers in general the relevant impacts on professional and personal life for those who decide to work in the third sector, whether on a contracted or voluntary basis. Specifically, to show the relevant impacts for those who decide to work in the third sector; to compare the 1st sector, 2nd sector and 3rd sector and to present the results of the lack of quality of life at work.
