Business entities strive for continuous adaptation to changing situations and needs. The decisions of business entities entangled in multifaceted processes of economic, social, and environmental progress must be taken on the basis of reliable knowledge, developed know-how, scrupulous recognition of the initial state, and foresight of the multiple consequences of business actions over a long horizon. In such a situation, the measurement of financial efficiency in terms of the profitability of enterprises in meat and poultry industries is extremely desired and provides valuable information on the necessary modifications to reduce the potential risks of business operation. The Polish meat and poultry industries should take into account current and future market requirements, competition, and consumer response. The dynamic progress of technology is forced to take appropriate steps to improve and modernize products, services, and methods of solving profit losses. The aim of the paper is to calculate and evaluate the statistical relationships between profitability ratios in Polish meat and poultry enterprises divided into four groups: slaughterhouses, meat enterprises (small, medium, and large), poultry meat enterprises, and meat trade enterprises. In the theoretical part of the study, methods of descriptive, comparative, deductive, and synthetic analyses were used. In the practical part of the study, panel data from the entire meat and poultry industries in the period from 2010 to 2019 were used. For the measurement of financial efficiency, methods, such as financial indicator analysis, panel database modeling, and nonparametric ANOVA, were applied. The ANOVA method was used to test only the statistically significant relationships between profitability ratios across all groups of examined enterprises in the meat and poultry industries. To summarize, the optimal level of profitability was achieved by all groups of examined enterprises, except small meat enterprises. The highest financial efficiency in the area of profitability was reached by poultry enterprises. Moreover, financial support for small companies in the meat industry can bring tangible benefits such as maintaining a diversified product range locally and transforming small meat companies into buying centers for the local community. Both are effective solutions, especially in view of the post-pandemic situation.

The issue of the efficiency of food processing enterprises is ever-present because of the continuous process of improving the quality standards of raw materials, complying with the procedures in food production, introducing modern production technology, and, above all, due to the large number of actors who are competing for customers in the domestic and foreign food market. In the coming years, the Polish food processing sector will be facing significant challenges with the inevitable slow and gradual decrease in the cost advantages of raw material prices as well as ready-to-eat products. Manufacturing businesses, in the long run, will need to determine the efficiency, and hence the competitiveness of the Polish food processing sector. The aim of this paper was to review the domestic and foreign literature in terms of the classification and systematization of the concept of eco-efficiency and to find the most optimal set of eco-efficiency measures based on the research in chosen food processing enterprises in Poland. In the theoretical part of the study, methods of descriptive, comparative, deductive, and synthetic analysis were used. In the practical part of the study, appropriately selected qualitative methods, such as a questionnaire, were presented. The results of the analysis were based on the results of the authors’ own calculations, as well specific findings from business practice, both from inland and abroad.

This article explores outplacement models typical for understanding the roles of job insecurity and the subjective perception of opportunities to find a new job. This study aims to validate the following hypothesis: people who are covered by outplacement systems in a workplace usually feel that they have both a good opportunity to find a job and have low job insecurity. Outplacement was defined according to a matrix of job insecurity and the possibility of finding a job. This comparative study is the first one that investigates the differences in outplacement and was carried out taking into account job insecurity and job opportunities. The Job Opportunity Index was almost the same in Russia and Poland but the Job Insecurity Index in Poland was higher than in Russia. 51% of Russian bankers and 29% of Polish bankers indicated that they could count on outplacement services to help them. The hypothesis was not confirmed in Poland as it was in Russia. The hypothesis of this study is supported by empirical research carried out on a sample of 2324 bank employees in Poland and in the Russian Federation. Factor analysis, discriminant analysis, the Mann-Whitney test and the Wilks’ Lambda test were used.
