“…The problem of ergonomics of manual work positions, characterized by high loads on the human body, is relatively often raised and the actions of employers in this matter are sometimes visible. Unfortunately, these activities, as well as the activities of scientific communities that raise ergonomic problems at workplaces (Koszembar-Wiklik et all., 2015;Bartnicka et all., 2017;Bartnicka at all., 2018;Mleczko, 2016;Winnicka-Jasłowska, et al 2017;Kuboszek at all., 2018;Żabińska and Kuboszek, 2018;Kabiesz and Bartnicka, 2018;Bartnicka at all., 2018;Matuszak and Żabińska, 2018) do not bring the expected effects. The main problem is still the low awareness of employees about the principles of ergonomic work.…”
