In recent years, the scale of bullying has been constantly growing. The actual size of this phenomenon is very difficult to determine. People experiencing bullying are ashamed or afraid to admit that they have become victims of bullying. The purpose of this article is to introduce a definition and present causes, consequences and methods of preventing and dealing with bullying. Without a doubt, the current situation in the labor market, i.e., rising unemployment, difficulties in finding new jobs, is conducive to the development of this phenomenon. Employees want to keep their jobs at any cost.

In Poland, there are at least 31 important pathogens (viruses, bacteria, fungi, protozoa, helminths) causing occupational zoonotic diseases other than tick-borne. Of that number, 9 are transmitted mainly by airborne route, 9 by alimentary route and 13 by direct contact through the skin and/or mucous membranes. The main directions in preventing zoonoses include keeping animal rooms clean and conducting periodic disinfections, using protective clothing and equipment, medical prophylaxis, eradicating endangered flocks, combating rodents, vaccinating humans and animals, taking precautions at parturitions of ruminants, maintaining hygiene at food and water consumption, and health education.

Practical experience of the staff of CIOP-PIB’s Centre for Certification of Products related to conformity assessment of personal protective equipment (PPE), as well as questions and doubts with which entities interested in placing those products on the market apply to the Centre, point out that it is necessary to clarify some issues connected with conformity assessment procedures of individual categories of PPE.

Using protective devices and guards in machinery is an obligation resulting  not only from  regulations but also from a kind of moral dictate, since those devices and guards should protect machine operators against risks. Defeating protective devices consists in introducing changes into the design of machines, following which  they do not protect employees any more. CIOP-PIB's studies showed that protective devices were defeated in practically every factory. The first part of this article presents results of an analysis of accidents caused by defeated protective devices; it also analyses the extent of this phenomenon on the basis of study visits and questionnaires. The analyses showed that  over 20% of  accidents related to machine operation resulted from defeated protective devices. Those accidents were usually serious or fatal. Moreover, study visits and questionnaires showed that defeating protective systems was common. The next part of this article will suggest a method of preventing this phenomenon.
