Since 1997, Brazilian food sector Union movement, researchers working in the field of occupational health at several Universities and several Universities and members of the Public Ministry of Labor (MPT), have sought general improvement of working conditions in meatpacking plants. After 10 years of study, negotiations, scientific advances and political pressure, with broad government involvement, organized workers and employers, this effort was topped with the publication of the Regulatory Norm 36 (NR 36) in 2013, which established a series of obligations and monitoring parameters of working conditions in the meat slaughtering and meat and by-products processing sector, resulting in a great reduction in occupational accidents and illnesses. Several illnesses, work disabilities and deaths have been demonstrably prevented in these environments.

Since then, the NR 36 has been improved, with the publication of small adjustments and attachments that have further improved its power of control and protection against occupational risks in the meat packing plants. However, following the recurring initiative of the current government, with the misleading and pompous name of “harmonization and modernization”, several changes are being implemented in the legislation, especially in the Regulatory Norms that regulate health and safety conditions at work, elaborated in offices, with restriction of the broad and democratic participation of workers and/or their representatives, strongly aligned to the employers’ demands in general.

In several of the amendments in the Regulatory Norms (NR) already republished, it’s noticeable the lowering of the standards provided for in the basic legislation of these norms, which dates back to 1978. For the most part, such changes occur in line with the dismantling of Labor Rights, since the so-called Labor Reform of 2017.

It is precisely on the issues that this manifest warns: the lowering of health and safety standards at work in general and specifically at meatpacking plants, represents a major social setback, since the normative reference in force is the result of decades of advances and improvements in these environments, and its hasty amendment will worsen working conditions, with the return to alarming rates of sick leave caused by incapacity, due to occupational reasons that were not recognized by the organizations or by the Brazilian National Institute of Social Security (INSS), very frequent before the Norm was published. It should be noted that such sick leaves had perverse repercussions by their association with the suffering, impoverishment and loss of social rights of workers and their families, associated with the financial impact transferred to society, directly burdened by the increased social security benefits such as disability benefits, worker’s compensation, disability pensions and death pensions, as well as medical expenses in treatment and rehabilitation, mostly assumed by SUS (Brazil’s Public Single Health System). Intangible social costs represented by pain, chronic disabilities, limitations to return to work under appropriate conditions, and the condemnation to social security dependency, far more serious, cannot be measured in currency!

Overall, it’s an outrageous injustice to naturalize the disposal of young people, in the fullness of their productive phase, who are referred to the INSS end up being chronically away from work, with costs paid for by society and not by those who have harmed them.

Therefore, we defend that at this time, no hasty changes in health and safety legislation should be made, without appropriate technical support on each topic addressed by the different NRs.

Changes in legislation require that, before any amendments are made, the contradictions that the dynamism and complexity of the world of work place on a daily basis for workers are overcome, such as ensuring a better balance between production requirements and workforce. Other possibilities for virtuous, even if temporary, changes include reducing working hours in unhealthy places and increasing work breaks as a compensatory measure for intensifying work.

The evolution of labor relations to more balanced and sustainable models, goals already achieved in other countries, indicates that the increased participation of workers and their entities in the management of prevention programs developed by companies, as well as initiatives of humanization and enhancement of labor relations, which include increasing the autonomy of workers, are civilizational advances that benefit all stakeholders, and move away from the shadow of barbarism, logic that seems to guide some of the current proposals for regulatory revisions.

We call on all those who share this same understanding and indignation to support and participate in this protest!

This is our manifest.
