The objective of the paper is to present an original (own) concept of a model profile of a sustainable manager from the sustainability perspective and then confront this model profile with the opinions of managers employed in energy companies. This problem domain has not been reflected in the scientific literature. Sustainable managers are the ones who are fully prepared to implement the principles of sustainability in energy companies, respecting the principles of sustainable management. Their activity can, to a considerable extent, accelerate sustainable development. According to the model profile, a sustainable manager should be sensitive to ecological and social problems; be knowledgeable about sustainability and demand the same from subordinates; comply with ethical standards; implement pro-environmental and pro-social innovations; and also plan, organize, motivate, and control the contribution, in this way, to sustainable development. Research was conducted aimed at discovering the views/opinions of energy companies’ managers pertaining to the above-specified model profile of a sustainable manager. As the research demonstrates, managers assign various significance to the analyzed traits and actions. The largest number of managers recognized the following to be the most important for them: compliance with ethical standards (86.1%), planning and organizing in accordance with the principles of sustainable development (52.8%), and being knowledgeable about sustainable development (38.9%). The paper contributes to the trait theory of leadership and the theory of sustainable management. It is also of practical value—it can prove useful in the processes of educating, recruiting, and evaluating sustainable managers.

Customer security in the e-commerce sector is not, but should be, approached in terms of sustainability, because it is a social problem concerning more than 2 billion people worldwide and over 20 million shopping sites. New techniques and technologies are implemented in this sector not only by e-sellers, but also by cybercriminals, which significantly lowers the level of its security. The purpose of the paper is to present, on the basis of own research, the main e-commerce threats from the perspective of the customer and the seller, and to indicate the possibility of their elimination, which should contribute to sustainable development. The threats from the e-customer’s perspective were identified by considering individual phases of online purchase. In the case of e-shops, the threats were analyzed in a personnel—computer hardware—software structure. As conducted research shows, the threats for e-customers are located in three main areas: security of the means of payment, security of personal data and payment cards, and security of purchased goods. The security of the e-customer largely depends on the security of the e-store in which the purchase is made. Research has shown that e-stores are not fully secure, which mainly results from negligence and the lack of knowledge in the sphere of cybersecurity.

Until the outbreak of the COVID-19 pandemic, virtual tourism was not as popular as during its duration in 2021, when traveling in the real world was not possible due to social isolation and forced quarantine. In response to the lockdown and the lack of freedom of movement around the world, tourists decided to travel in cyberspace during the COVID-19 pandemic. In this way only, and without leaving home, could they visit tourist attractions, watch museum exhibitions, participate in various media events and take virtual walks. After the “unfreezing” of tourism, the time has now come to adapt tourism to the post-pandemic normality. The aim of the paper is to discover whether the new trend of online tourism that developed during the pandemic will stay with us forever and how it will evolve, especially for Generation Z, who are just entering the labor market but who, at the same time, will determine the future of tourism soon. The research results show that as the pandemic restrictions disappear, the need to experience various forms of tourism in places previously viewed in cyberspace (virtually), occurs among the representatives of Generation Z. Thus, virtual tourism is a form that precedes and complements a real journey. The qualitative method was chosen for the research conducted in Poland. The research was carried out in 2022. A total of 40 focus groups of 7 people each (N = 280) participated in the research. They consisted of Generation Z representatives born after 1995; the oldest of them will be 27 in 2022. In parallel, the method of in-depth individual interviews was used in the research. In order to reach the participants, a non-random sample was chosen using the “snowball” method. In total, 100 people took part in the in-depth individual interview. The two-track research allowed to obtain a total sample of N = 380.

The future of the energy sector depends on the younger generation. The paper presents the results of the study, the aim of which was to determine to what extent younger generation is pro-ecological and pro-social, and whether they will include pro-ecological and pro-social activities in the management of energy companies. It is especially important to implement sustainable management in the energy sector. The study found that only 33.9% of young people are highly pro-ecological and 28.6% highly pro-social. As many as 83.0% of the younger generation show low and medium interest in environmental protection. Declarations of young people concerning high degree of inclusion of pro-ecological and pro-social activities in management are at the level of 49.9% and 58.1%. However, in many cases, these intentions do not coincide with the high pro-ecological and pro-social attitude of young people. This means that their future activity for sustainable management may be low. According to the survey, the younger generation to a large extent is not prepared to continue efforts for sustainable development in the future in the energy companies.

Różnice kulturowe wpływają na kształtowanie relacji oraz współpracę w międzynarodowym biznesie. Mają one bardzo duży wpływ na komunikację niewerbalną, która uzewnętrznia się podczas każdego spotkania "twarzą w twarz" partnerów biznesowych oraz w trakcie prowadzenia przez nich rozmów za pośrednictwem urządzeń elektronicznych z funkcją wideo. Błędy popełniane w komunikacji niewerbalnej stają się źródłem nieporozumień, a nawet szoku kulturowego. W ich wyniku relacje między partnerami biznesowymi zostają zakłócone, co negatywnie wpływa na dalszą współpracę. W artykule przedstawiono szerokie spektrum zachowań niewerbalnych oraz zaleceń, których uwzględnienie w komunikacji z cudzoziemcami zapobiega zaburzaniu kontaktów biznesowych na arenie międzynarodowej.
