The aim of this paper is to examine individual social remittances in the sphere of employment, against the background of the changing employment patterns and flexibilisation of work. Through an analysis of life stories of post-accession return migrants from the UK to Poland, it investigates the way in which returnees’ work experience gathered abroad impacts on their perception of employment standards in general. The revealed differences are understood as ‘potential social remittances’, i.e. the discrepancies acknowledged by returnees between the realities experienced during emigration and after their return (in this case to Poland). It is argued that the actualisation of the ‘potential social remittances’ depends on return migrants’ coping strategies as well as on the institutional and structural settings in returnees’ home country. The four main distinguished strategies are: re-emigration, activism, adaptation and en-trepreneurship.

The article presents the results of research carried out in construction companies among employees involved in the organisation and management of construction projects. The research concerned factors and their impact on decisions regarding the planning of quantitative employment workforce at a construction site. Based on individual assessments of individual factors, average assessments were calculated and hierarchies of the factors examined were made. In the second part of the article, the dispersion coefficient of relative classification was used to assess the reliability of the opinions collected. The content presented is a continuation of the work of the authors on the subject of employment planning at the construction site.

Recently, in most developed economies, the average age of the workforce has been growing rapidly. Therefore, the questions arise how will it affect the level of wages and the shape of age-productivity and age-wage profiles. The aim of the paper is to analyse the relationship between changes in the age structure of the employment and wages of individuals in minor occupational groups. Using individual data from the Structure of Earnings Survey in Poland in 2006-2014 we created an unique database of individual wages and the characteristics of employed in occupational groups at 3-digit level of classification. In our analysis we used an extended version of Mincerian wage model where both the characteristics of employees (education, work tenure, age, gender, and type of employment contract) and employers (size and ownership sector) were taken into account. The results for the whole sample indicate a significant and negative relationship between the proportion of older workers in employment in a given occupational group and individual wages. However, when the analyses were performed separately for each of the 1-digit occupational groups, the results varied significantly. In those groups where knowledge and qualifications of employees are more important than physical strength had to be updated permanently, an increase in the number of the older workers raises the average wages.

Between 2014 and 2016 the number of foreigners on the Polish labour market increased by over 300 per cent. They were mainly Ukrainian citizens taking up seasonal employment on the basis of the so-called ‘sim-plified system’. According to the literature, such a large increase in labour immigration in a short period of time may be an important factor in the growth of unemployment and the reduction of the employment rate of natives. The main purpose of this text is to show the correlation between the increase in the employment of foreigners in Poland and to determine whether or not this has had an impact on the deterioration of the state of the labour market. For this purpose, data from the Central Statistical Office and the Polish Ministry of Family, Labour and Social Policy were collected. As a result of our analysis, it was found that the significant increase in the presence of foreigners on the Polish labour market, which the country has faced in recent years, was not correlated with the rise in unemployment, the increase in the rate of economic inactivity and the availability of seasonal jobs. On this basis, we can state that the increase in the supply of foreigners on the Polish labour market, compared to other factors influencing it, was weak enough for the negative effects of the increased employment of foreigners to not occur.

The present paper examines how, at a time of post EU-enlargement migration, female Polish migrants in the UK act within, despite and against the social structure of gender regimes in the origin and host societies and how female migrant agents are actively mediating structures in a quest to fulfil their as-pirations. Biographical narrative interviews conducted with female Polish migrant workers in the UK and semi-structured expert interviews provide the empirical data for the analysis of how employment trajectories in migration can challenge or reinforce gender roles, and of the role of female migrants’ agency. The paper shows how some women are limited in their opportunities by gender roles and fa-milial obligations, while others are able to progress professionally either by entering a typical ‘mi-grant’ sector, by undertaking UK education, or by starting their own businesses, challenging the gendered expectations they face. The paper thus contributes to the discussion on female migrants as disadvantaged migrant workers or as active agents of change.

In contrast to the usual integration of migrant workers in the ‘bottom jobs’ on the labour market, the em-ployment of Ukrainian workers in Hungarian electronics plants seems to take place in a more beneficial way. With the active mediation of temporary (temp) agencies, Ukrainian migrant workers are offered regular blue-collar assembly work, together with the same social rights and benefits as their local Hungarian col-leagues. Relying, in our analysis, on the literature on industrial sociology, migration research and global value chains, we are developing a critical perspective in which migration and employment are not seen as separate spheres but as mutually reinforcing each other. We combine bottom-up empirical research based on interviews with workers and a sectoral inquiry on industrial and employment relations in the temp agency sector supplying multinational corporations. Our main argument is that complex contracting also means subtle controlling. Such contracting is not the cheapest form but it creates a different, efficient employment regime with dependent, controllable, flexibly available, ‘fluid’ employees. Employee respondents described their position as dependent, ‘out of control’ and a temporary earning opportunity. Devoid of clear mecha-nisms for controlling their work conditions or growth within the job, all respondents turned to a more instru-mental approach, in which they invested in building up social capital through friendships, networks and personal relationships. Obtaining Hungarian citizenship and learning the language were two other main strategies for dealing with insecurity. Their efforts correspond with and reinforce a more globally integrated but ethnically motivated immigration regime, characteristic of post-socialist Hungary.

The article proposes the use of a synthetic indicator in spatial research. In the construction of synthetic indicator, it assumes that the indicator should not only specify the synthetic value based of on empirical data, but also show its structure. The structure of the indicator should answer the question to what extent individual empirical measures influence to the value of a synthetic indicator. Using the rules of statistical grouping, four groups of voivodships with different economic potential were distinguished. Research shows that on the synthetic indicator of voivodships (in particular groups) were affected to a varying extent by the values of empirical variables: number of employees, value of fixed assets, value of gross domestic product, number of economic operators.

The article examines the trends in the development of renewable energy in Ukraine in accordance

with the long-term strategy of the energy sector of the state in the context of the transformation

of employment in the energy sector of the country. It is emphasized that investments in renewable

energy technologies create more jobs compared to traditional electricity generation technologies.

It is defined that in Ukraine there is a significant untapped potential for energy efficiency, which

requires accelerating the pace of modernization and development of renewable energy sources and

raises the issue of labor supply to the industry. It was emphasized that there are a number of opportunities

for the development of the energy sector of Ukraine related to the development of renewable

energy sources. It is underlined that the formation of territorial-industrial clusters in Ukraine

for the production of equipment for solar and wind energy with a closed production cycle forms

long-term prerequisites for socio-economic stability in the country and stimulates employment. It is

substantiated that an important reserve for increasing employment in Ukraine is to ensure the energy

efficiency of buildings. At the same time, it was noted that in the field of renewable energy and

energy efficiency in Ukraine there is a significant shortage of qualified technicians and specialists

in the field of innovative technologies, which confirms the importance of studying the problem of

labor support in the industry. It is determined that today the solution of the issue of labor supply

of the industry takes place mainly at the level of enterprises that invest in the development of their

own staff.

This paper presents the situation of coal mining in Slovakia, focusing on the social-political aspects and environmental aspects of its sustainable development. In recent years, the mining of lignite and brown coal in Slovakia has been closely linked to the production of electricity and heat in the Novaky power plant. Domestic brown coal production covered more than three quarters of demand in the Slovak Republic in the last few years. The sustainability of coal mining in the coming years in Slovakia is closely associated with raw materials reserves, new mining technologies, the development of the Novaky power plant, and the government's commitments to national economic interests through securing the energy supply or state aid. Of course, of these factors must be considered in the context of international obligations, such as those related to climate and environment, particularly air protection.

The three most important Slovak brown coal deposits are located in the Upper Nitra Basin. This territory includes areas in the 5th and 4th degrees of environmental quality, signifying a disturbed and very disturbed environment. Since coal is expected to remain the dominant fuel for electricity generation araund the world, and in particular for many of the countries of Central and Eastern Europe, it is necessary to create conditions for the environmental sustainability of coal mining in the coming years within the context of international obligations. Both the security and the stability of the electricity network in Slovakia and maintaining employment levels in the Upper Nitra region play important roles in this discussion.

Underground coal gasification (UCG) is a newmining technology and a technology for gas recovery in situ.

A comprehensive evaluation of the impacts of underground coal gasification was carried out in addition to summarization of the expected impacts in terms of the significance and distribution of the time period.

Based on a comprehensive assessment of the proposed action, it can be stated that it could bring a socially unacceptable risk to the area, specifically the significant impairment of health or the environment (groundwater and nearby hot springs in Bojnice). The implementation of operations could affect the opulation's health, since the partition is placed in close proximity to residential areas.
