Mental Health and bank workers in Brazil: a systematic review of scientific literature in the last twenty years

Introduction
In recent decades changes in the Brazilian banking system have occurred with the establishment and implementation of computer technologies, self-service systems and home banking, which have modified the workers activities with the downsizing of workstations. In the 1990s, bank workforce decreased 40%. In the same time, we have seen the privatization of public banks. All changes can affect physical and mental health workers. Mental health is built through the cognitive and psychological dynamics surrounding social relations and the work constitutes its central pillars.

Methods
The method applied in this work is systematic review of scientific literature. We analyzed scientific publications in Brazil in the last twenty years.

Results
The most frequent complaints are muscle pain, feelings of insecurity, alienation, powerlessness, devaluation, loss of previous status, and the fear of unemployment when workers cannot reach the targets set by management. Data from National Insurance shows that between 2000-4, 5355 banking workers had health problems and took sick leave for 15 days (almost 2% of the national total). The severity of the absenteeism is indicated by the average sick days, 442 days, and nearly twice the national average. Moreover, they generate a high cost, twice the overall national average. The most prevalent diseases are musculoskeletal disorders and mental illness. In the 1990s many suicides were recorded in this category, which coincided with the privatization and restructuring of public banks.

Discussion
In the last years, the degradation of work conditions in Brazilian banks was determinant to increase the incidence of occupational diseases, work-related mental illness and absenteeism among workers. Moreover, we note the work intensification with increased density, the additional tasks, such as 'selling bank products'. In this situation, we consider a challenge: how to work the prevention of illness with these workers given these work conditions.
