Bullying at work is a long-standing area of research interest that requires investigation of the role of the individual exposed to systematic negative behaviour. Studies using cross-sectional samples and broad personality measures have found some distinguishing personal characteristics of employees who are bullied compared to others. Few, however have applied theoretical frameworks to explain why personality can play a part in why an individual ends up at the receiving end of bullying and harassment at work. This article applies an overall and specific theoretical model, the vulnerability thesis, to investigating the role of temperament in relation to workplace bullying. The results show that (1) some employees exposed to bullying at work also acted as perpetrators (provocative victims), that (2) exposure to bullying at work is connected with temperamental emotional vulnerability, and that (3) hostility and self-oriented aggression mediate the role of personality in the form of temperament in relation to workplace bullying. Strengths and weaknesses and potential practical implications for helpers of employees exposed to bullying at work are discussed.
The development of economy and industry introducing new technologies and materials often means the increased threat of occurrence of factors harmful to humans and environment. Workers employed in foundries as mould pourers are the group of high professional risk. Foundry moulding sands when poured with liquid metal are a source of the emission of harmful, toxic and carcinogenic (benzene, PAHs) compounds. The paper presents the results of studies on the concentration of chemical compounds emitted in the process of casting aluminium alloy and brass using moulding sands with the new inorganic binders. The specific values of the exposure indices were compared with the limit values. This enabled an assessment of the impact of moulding sands on work environment. The obtained results were compared with the values of contaminants emitted when pouring foundry moulds made from furan sands and bentonite sands with an addition of coal dust. Studies were carried out under the project POIG.01.01.02-00-015/09 "Advanced materials and technologies."
