In the staffing agency business, the responsibility of the working environment are divided between the client companies and the staffing agencies. Therefore the temporary workers should be double protected, but the consequences are that the responsibility of the working environment falls between the cracks in many businesses.The purpose of the essay is to examine how the workers in industrial businesses from the staffing agency are protected by the shared responsibility that exists between the client companies and the staffing agencies, regarding work environment. To be able to answer this questions, the legal method is used.The conclusion of this essay is that the temporary workers are protected by the Work Environment Act, stating that the staffing agency and the client company have a responsibility for the employee´s work environment. Since the staffing agency is the employer, they have the largest work environment responsibility. This means, however, that staffing agencies are in a special situation because they are not in the place where the employee works. Since the client company is equated with an employer according to 1 § SAM, the systematic work environment is shared equally between the client companies and staffing agencies. On the grounds that there is a lack of clarity concerning who is responsible for what from the both parties, it leads to that the working environment responsibility are neglected. It also depends on the fierce competition that exists between various staffing companies today, which means that staffing companies do not always take part of the client companies' risk assessments or requirements on the grounds that they are afraid of losing the customer. This results that the temporary employees do not get the protection that the Work Environment Act is intended to give them.

[pt] Nesta tese, proponho uma discussão sobre o trabalho de Rogério Duprat como arranjador de canções tropicalistas e sobre o modo como alguns de seus arranjos musicais dialogam com as palavras cantadas com as quais eles foram gravados no final dos anos 1960. Combinação de sons orquestrais, de clichês da música de cinema e de efeitos sonoros variados, os arranjos de Duprat conferem um caráter sonoplástico às gravações tropicalistas. Experiente compositor de música serial, eletroacústica e para computador, assim como de jingles e de trilhas sonoras para o teatro e o cinema, Duprat valeu-se de amplos conhecimentos da música de concerto europeia e da música popular do Brasil para fazer referências em seus arranjos a diversas obras e estilos musicais. Como um artífice, procurou compreender e responder às demandas dos compositores de canção, dos cantores, do produtor da gravadora, dos técnicos de gravação e de outros profissionais que acabaram por se tornar coautores de seus arranjos. Arranjos que também foram produzidos sob influência de agentes como John Cage, The Beatles, os poetas concretos e os compositores, regentes e instrumentistas do Música Nova, grupo paulistano de vanguarda de onde saíram Duprat e os demais arranjadores de canções tropicalistas. / [en] In this dissertation, I examine the work of Rogério Duprat as arranger for tropicalista songs and the way some of his musical arrangements dialog with the melodized words with which they were recorded in the late 1960s. As a mix of orchestral sounds, film music cliches, and sound effects, Duprat s arrangements give an audiovisual character to tropicalista recordings. As an experienced composer of serial, electroacoustic, computer, and advertising music, as well as theater and cinema soundtracks, Duprat employed his broad knowledge of Western concert music and Brazilian popular music in order to make audio references to diverse works and music styles interwoven into his arrangements. As a craftsman, he sought to understand and to answer the demands from song composers, singers, the record company producer, recording technicians, and other professionals that became collaborators of his arrangements. His arrangements were also influenced by agents such as John Cage, The Beatles, the concrete poets, and the composers, conductors and musicians of Música Nova, a São Paulo avant-garde group that was integrated by Duprat and the other arrangers for tropicalista songs.
