NR-36 Cold Plant Break min

NR-36 Psychophysiological Breaks in Slaughterhouses and Meatpacking Plants

Brazilian Regulatory Norm NR-36 (Ministry of Labor, 2013) covers health and safety in the slaughtering and processing of meat and meat by-products. Anyone working in artificially cold environments (cold chambers, freezing tunnels, deboning rooms below 12°C) gets a psychophysiological break of 20 min for every 1h40min of continuous activity, and that's on top of lunch breaks. To get the total daily pause in minutes the formula is floor(workHours × 60 / 100) × 20.

Beyond the breaks, the norm asks for job rotation across workstations that load the body differently, an Ergonomic Work Analysis (AET) for each cell, and medical exams (both at hiring and periodically) aimed at catching musculoskeletal disorders early. Checking that all this is honored falls to the Labor Auditors and to unions like CONTAC (Confederation of Food & Beverage Workers).

Applications

HR and SST teams at JBS, BRF, Marfrig, Aurora and other meatpackers reach for a calculation like this when sizing break rooms, arranging who covers a shift while people are on pause, getting ready for a labor inspection, fighting RSI/WMSD lawsuits (LER/DORT in Portuguese), or sitting down to negotiate a collective agreement with the food workers’ union.

FAQ

Do the 20 minutes count as worked time? They do. NR-36 item 36.13.2 says the psychophysiological pause counts as effective working time for every legal purpose, overtime and rest pay included.

Can pauses be aggregated at the end of the shift? No. They have to be spread through the shift, one after each 1h40min block. Saving them all for the end misses the ergonomic point entirely, and the Labor Inspection will fine you for it.

Is the rule the same for office staff inside cold plants? No. The 20/100-min rule is for people making repetitive cuts or handling carcasses in the cold. Administrative staff stick to the standard intra-day breaks under the CLT.
