In recent years, sustainability has become increasingly important in a company's image. Customers are becoming more environmentally conscious and demanding that the companies they do business with are also taking steps to reduce their environmental impact. By adopting sustainable practices, companies can demonstrate their commitment to positively impacting the world and building customer trust. This scientific article aims to contribute to a better understanding of the role of sustainability in shaping consumer perceptions of a company's image and provide insights that can help companies develop more effective sustainability strategies and build stronger brand images. The study utilised general scientific methods for processing data, and the data obtained from the online survey were assessed using mathematical-statistical methods and statistical hypothesis testing. Sustainability has become an important aspect of a company's image. With increasing environmental awareness among consumers, companies are expected to take responsibility for their impact on the planet and society. Sustainability in a company's image has become an important aspect of its brand identity, and it can significantly impact its reputation, success, and long-term viability. Consumers are increasingly concerned about the environmental impact of the products they buy and use, and many of them have started to prefer companies that use sustainable practices and produce eco-friendly and sustainable products over those that are not. Companies that embrace sustainability and prioritise environmental and social responsibility are more likely to thrive in a rapidly changing business landscape where consumers are increasingly interested in sustainability and ethical practices. By embracing sustainability, companies can create a positive reputation, build customer trust, and drive long-term success. The added value of the scientific article is that it provides valuable insights and strategies for practising sustainable marketing, which helps to build the company's image. By analysing the impact of sustainability on a company's image, we contribute to the opportunities for companies to improve the brand image and reputation of the company, which can positively increase customer loyalty and trust and gain a competitive advantage in their industry. Therefore, this scientific paper can provide businesses with valuable insights to differentiate themselves from competitors, attract new customers, and increase profit.

Research purpose. Currently, the Internet is used by almost 5 billion users worldwide, of which 80% actively use at least one of the social networks. And marketing managers are well aware of this fact, as they had to switch to a new way of attracting potential customers. One of these methods is also influencer marketing as a form of marketing communication. In influencer marketing, the emphasis is placed on influencers with a significant impact on the community on which marketing activities and campaigns can be oriented. It is a method of non-violent and natural promotion of a product or brand, which acts on the consumer as a natural part of the space in which it is located. Especially one generation of consumers, Generation Z, is considered to be the target segment for influencer marketing due to their digital skills and inclination to social networks. The main aim of the article is to determine the impact of influencer marketing on the decision-making process of Generation Z. This also includes providing the theoretical background and analysis of influencer marketing from the viewpoint of Slovak and foreign authors. Design / Methodology / Approach. General scientific methods were applied for the processing of the data as well as mathematical-statistical methods to evaluate the data collated from the results of the questionnaire survey and to statistical hypothesis testing. The important source for secondary data was scientific research, annual company reports, statistical databases, and published professional publications. In order to find out the impact of influencer marketing on the decision-making process of Generation Z, a questionnaire survey was conducted. Findings. A successful marketing campaign on social media in cooperation with influencers requires the correct selection of the influencer according to their follower base, profile focus, credibility or reach, which is measured by Engagement rate. The number of followers is not as significant as the relationship that the creator has with their fans. When choosing an influencer, it is also necessary to take into account the way they promote products, ask them for originality and creativity, and prefer long-term collaborations to one-time contributions. These steps can bring a lot of benefits to the company, from which it will subsequently profit. Based on the analysis and results of the questionnaire survey, it is thus clear that the implementation of influencer marketing in marketing communication of Slovak companies targeted at Generation Z brings many benefits, including building relationships with Generation Z, increasing their loyalty and improving the company image. Originality / Value / Practical implications. Finally, measures for effective influencer marketing usage targeted at Generation Z are proposed, and its benefits are highlighted.

Providing conducive working conditions is essential for fostering the personal and career growth of employees, ultimately ensuring their psychological well-being. This study aims to investigate the impact of workplace conditions on the psychological well-being of university teachers in Slovakia and to examine how factors from the Luxembourg Workplace Mobbing Scale (LWMS) function as moderators in this relationship. A questionnaire survey collected data from 687 respondents, and the analysis included reliability and moderation tests, with a one-way ANOVA confirming the model’s significance. The findings indicate that workplace conditions significantly affect the psychological well-being of university faculty, with LWMS factors—criticizing, ignoring, meaningless tasks, ridicule, and conflicts—moderating this relationship. A limitation of this research is the reliance on the LWMS, which comprehensively addresses bullying but encompasses only five factors. This study contributes to the understanding of workplace bullying and its impact in academic settings, offering implications for theory and practice in fostering healthier work environments in higher education.

Currently, much attention is paid to digital transformation in all areas, including the public sphere. The latest studies show that it is necessary for the public sector to monitor the efficiency and satisfaction with the services provided. However, there are significant gaps in research in this area, including in Slovakia. This research proposes and applies the measurement of efficiency using the DEA method in the context of e-Government, provides a comparison of the roles of states in the use of public electronic services in the EU, and applies the method of measuring satisfaction using the American Customer Satisfaction Index, focused on the central state portal in Slovakia. The main methods that were used to fulfil the objectives of the work were data envelopment analysis, “DEA”, and the American Customer Satisfaction Index, “ACSI”. Other methods used include the Mann–Whitney U test, the chi-squared test, and Sperm correlation analysis. From the results of the work, it is possible to conclude that ACSI can be applied within Slovakia. Furthermore, the results show a strong correlation between perceived quality and satisfaction, which is 0.855. Overall satisfaction with the central state portal of public electronic services reached 61.7%. We conclude that it would be appropriate and possible to use ACSI as part of DEA measurement.

Unfortunately, social occurrences and practices that were deemed unwanted, bad, or even indecent merely a century ago are becoming more and more commonplace at the current stage of society's evolution. Bullying at work has an impact on many areas of business, including daily operations and the bottom line of the company. The aim of the research is to find out whether the factors of company size, corporate culture, and industry have an impact on the occurrence of pathological relationship in the workplace. The data were processed using the SPSS Statistics program. Pearson's χ2 test was used to test the hypotheses. The results of the research show that the size of the company and the industry have an impact on the incidence of mobbing. It is a weak, or in the case of the industry, a moderately strong dependence. In the case of organizational culture, the dependence was not confirmed.
