Hierarchical Analysis of Forms of Support for Employees in the Field of Health Protection and Quality of Work during the COVID-19 Pandemic and the Desired Post-Pandemic Forms of Support

Issues of employee support during the COVID-19 pandemic and the post-pandemic period are of an interdisciplinary nature. Moreover, these should be considered from both an epistemological and a practical perspective. The aim of this study was to determine what forms of support for employees in terms of health and quality of work were provided by employers during the pandemic and what forms of support will be expected by employees after it ceases. The research process was carried out in two stages: primary and secondary exploration and quantitative clarification. In the first stage, a systematic review of the literature and a critical analysis of the so-called grey literature was performed. In the second stage, computer-assisted telephone interview (CATI) methodology was used. Ward’s method was used for data analysis. The results showed that the COVID-19 pandemic forced employers to search for new solutions to enable the continuation of their business activities, which consisted of switching from the traditional form of work to a remote form. The transition to the remote work mode changed the approach to the forms of work support provided for employees, with particular emphasis on the health of employees and the quality of work. The changes in the forms of support for employees in terms of health and quality of work were either bottom-up or top-down. Employers tried to provide access to remote infrastructure as much as possible, but the consequences of remote work in terms of the physical and mental health of employees were rarely noticed or considered. After the pandemic, online health support and access to the appropriate equipment and tools for remote work are unlikely to be needed.


Introduction
The COVID-19 pandemic has disrupted well-established practices in every aspect of economic and social life, leading to attempts to adapt to this new, unexpected situation around the world. It forced the necessity of a new look at the possible methods of running a business, opening up to less than traditional forms of the functioning of enterprises in the production and service sphere, as well as for various public entities [1][2][3][4]. In many cases, it was necessary to search for solutions such as remote work practically overnight. Remote work was introduced by employers to reduce the risk of infections but was also 3 of 21 and employer support. It also became justified to study the psychological impact of the pandemic on employee productivity [22,23].
When looking at research directly related to the issue of supporting employees during the pandemic, one can notice that so far, there is a focus on the industry approach. The most frequent studies concerned the support of teachers' work [24], which is justified by the scale of remote learning, or support for hospital employees [25,26] and hotels [27,28] due to the above-average risk of transmission through direct contact with patients or clients. Unfortunately, there is a deficit in employee support research during a pandemic that takes into account a multi-industry approach, allowing for comparative inferences to be made. There is also a lack of research that would answer the question of what forms of post-pandemic support in the field of health protection and work quality are desired by employees. These research gaps prove that research on employee support in the field of health protection and quality of work used by employers during the COVID-19 pandemic and in the post-pandemic period is desirable not only for epistemological reasons, but also for pragmatic reasons.

Context of the Research
The subject of this research is the support system implemented for workers to maintain health and quality of work during the COVID-19 pandemic and the support system desired after the pandemic. Assuming that the pandemic affected the behavior of employers towards employees, the primary objective of the research is to determine how the pandemic affected the support system of employees in terms of health care and quality of work. The assumption (thesis) for the research was made according to the logic of abduction using a deductive-empirical approach based on formal logic (deduction and the formulation of logical conclusions based on the analysis of the literature) and inductive logic (induction from direct exploratory research).
To facilitate the primary research objective, two research questions were posed: -What forms of employee health and quality of work support were used by employers during the COVID-19 pandemic? -What forms of post-pandemic support for health and quality of work are desired by workers?
It should be noted that the research problem concerns a current phenomenon with a history of only three years, which significantly determines the scarce state of knowledge in this field. This is confirmed by the literature review carried out. This deficit can be considered both in the context of the scientific problem and in the context of the research problem.

Stages of Scientific Reconnaissance
The course and structure of the research procedure was influenced by the nature of the objective defined at the theoretical level and was related to the lack of conceptualization and operationalization of the problem under study in the literature found to date. The research process was subordinated to abductive logic. It was conducted in two stages: the secondary and primary exploration and the quantitative explanation. The first stage was exploratory in nature. Its purpose was to justify the need for the research, to recognize the existing state of knowledge, and to identify gaps in the knowledge. In carrying out this stage, the following research techniques were used: a systematic literature review and a critical analysis of the so-called grey literature. The second stage of the research was aimed at providing empirical material to verify the validity of the adopted research thesis and to obtain answers to the research questions posed. This stage involved a computer-assisted telephone interview (CATI).

Participants
The target research sample was based on the indexation identified in the Polish Classification of Activities. The Polish Classification of Activities is the division of economic activities carried out by business entities in Poland. It was created for the purposes of statistics, recording, accounting, documentation, and use in official information systems and registers. It covers everyone who undertakes economic activity. It was developed on the basis of the NACE Rev2's statistical classification of economic activities, which was introduced by Regulation (EC) No. 1893/2006 of the European Parliament and of the Council of 20 December 2006. On this basis, a population of respondents amounting to 10,130 persons was selected. The population consisted of employees of enterprises. The following attributes were determined from the population: province, occupational situation, industry, employment in the enterprise, job position, and form of employment. The entire population was invited to participate in the survey, resulting in 2430 respondents, giving an effective maneuver rate of 24%. It can be considered that from a statistical point of view, the surveyed sample is representative of the population.

Data Collection
Individual structured interviews were conducted between May and June 2021 via a computer-assisted telephone interview (CATI). A pilot interview was also conducted to verify the correctness of the questions. The interviews were digitally recorded and transcribed verbatim.
The institution that collected the data for us has a designated data protection officer. This person represents the data protection organization. The data protection officer was mentioned in the market survey. In addition, the survey was anonymous. All survey invitations included information about the possibility to opt out of answering questions regarding data protection. Thus, the study was conducted in accordance with Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of individuals with regard to the processing of personal data and on the free movement of such data.

Data Analysis
One of the techniques belonging to the group of agglomerative methods, the Ward method, was used for this study [29]. The usefulness of Ward's method is evidenced by the fact that it has been applied in research by many authors [30][31][32][33][34].
Agglomeration methods gather elements into clusters. Clustering is the process of grouping (hierarchizing) data into classes (groups) or clusters according to the rule that the elements in the cluster are very similar to each other while simultaneously being very dissimilar to the elements found in other clusters. Cluster methods, or hierarchical methods, create a nested sequence of partitions, with a single, all-inclusive cluster at the top and single clusters of individual objects at the bottom. Each intermediate level can be seen as a combination of two clusters from the next lower level or as a partition and a cluster from the next higher level. The results of the hierarchical clustering algorithm may be represented graphically in the form of a tree called a dendrogram. This tree graphically represents the process of merging and intermediate clustering. It thus shows how the individual points merge into a single cluster [35].
Clustering methods are divided into two groups: agglomerative and partition methods. This classification depends on whether hierarchical decomposition is created in a bottom-up or top-down manner [36]. Agglomerative clustering combines members into clusters, and these clusters continue to merge into larger clusters to form a hierarchy of clusters. Partition clustering involves constructing different partitions, which are then evaluated according to certain criteria [37][38][39][40][41][42][43]. Thus, the rationale for using Ward's method is to combine elements into clusters so that the variance in the clusters is minimized.
As mentioned before, Ward's method is hierarchical, i.e., it divides the elements into a dedicated number of clusters. The clustering process takes place in stages. At the beginning, each element is independent, and then, step by step, successive elements are assigned to the cluster. In each step, the elements that are the "closest" to the identified clusters are taken into account. The number of steps may be from 1 to n, where n is the number of items analyzed. For 1, only one cluster contains all members, and for n, all members form their own cluster. It should be noted that once a cluster has been created, the elements of the new cluster cannot be split again [35].
For the purposes of our study, based on the methodology used by the authors [34,44], the Ward method was carried out according to the following steps: 1.
Normalization is usually applied because of the possible scale differences among the questions (j): where: x k, j -answer value (x) of the questions (j) concerning the users (k); x mj -mean of the answers (mn) regarding a question (j); s j -standard deviance (s) regarding a question (j); m k,j -normalized answer value (m).

2.
Designation of the distance (d) between two users or clusters (k and l) was calculated with the quadratic Euclidean distance using the normalized values for the total number of questions (q): 3. Users or clusters of minimal distance to each other are unified into a new cluster (k + l).
If the new cluster exists, its distances have to be redefined towards all other users or clusters (a). Different clustering methods use different algorithms for the calculation of new distances. The Ward method calculates the optimal minimum distance by taking into account the number of users in the clusters. where: N a -number of users (a) in the cluster; N k -number of users (k) in the cluster; N l -number of users (l) in the cluster.
The horizontal lines mark the stage at which the grouping was interrupted. The intersection was determined based on the analysis of the bonding distance in relation to the bonding steps (Euclidean distance).

Results
For the purposes of this study, 26 variables were considered regarding non-wage forms of employee support during the COVID-19 pandemic and expected support after its termination. Both offered and expected services were analyzed in terms of gender, age, size of the city in which the respondents live, the voivodeship in which the respondents live, the work situation they are in, the amount of employment in the company, the industry in which the organization operates, the position in which the respondent is employed, and the type of employment contract (70 variables). A voivodeship is the highest-level administrative division in Poland. We were interested in whether there would be variation in the responses by voivodeship. In Poland, there are differences between so-called northern and southern as well as western and eastern Poland, similar to in Germany or Italy. As the variables gender, age, and size of the town/city in which the respondents live did not show any correlation with regard to the subject of this study, they were omitted. The variables used in the analysis are presented in Tables 1 and 2. Before starting the analysis, it was examined whether the variables were dependent. As the responses obtained are measured on a nominal scale, Pearson's χ 2 test of independence was used to assess the dependency of the variables. All of the variables presented in Tables 1 and 2 met the required dependency conditions and thus could be used for further analysis.
For the sake of clarity, the graphs were divided into separate issues in order to illustrate the relationship between the categories of variables more easily. First, the relationships between the respondents' characteristics and non-wage forms of support offered by employers during the COVID-19 pandemic are presented (Figures 1-6).

Conclusions with Commentary
The issue of supporting workers' health and quality of work prior to a pandemic has quite often been considered within the framework of social responsibility [45][46][47][48]. Nowadays, another strand of research has emerged, in which the issue of health and quality support for workers is referred to as pandemic conditions.
The aim of the present research was to determine how the pandemic affected employee health and the quality of the support system during the COVID-19 pandemic and in the post-pandemic period. The results of the study allow the following conclusions: The COVID-19 pandemic forced employers to introduce new solutions to their practices by switching from the traditional form of work to a remote mode. Not surprisingly, this was the only sensible solution, as lockdowns in the early phases of the pandemic were in force in all countries, and companies could not or would not shut down.
The shift to remote mode consequently forced a redefinition of the forms of work support for employees. Due to the nature of the pandemic, particular attention was paid to health and quality of work, which may be due to the fact that these are key determinants of employee productivity and efficiency, although it may also be due to social rationale, i.e., the desire to take care of one's employee.
The change in the forms of support for employee health and quality of work was either bottom-up, when employees took the initiative, or top-down, when the initiative was on the employer's side.
While employers tried to provide access to remote infrastructure where possible, the consequences of remote work on employees' physical and mental health were rarely noticed or considered by them. This may result from the lack of knowledge on how to behave in this case and the lack of substantive preparation or lack of access to specialists.
Considering the form of employment, full-time employees stated that their employers did not provide them with safe conditions for remote work and did not provide online support for physical activity-this may be due to the fact that employers were surprised by the pandemic as well as by its scale and duration and did not have time to prepare for such a situation; in other words, they did not have the appropriate experience in this field. They did not have sufficient knowledge of how they could ensure safe conditions during periods of remote work. Additionally, the problem of physical activity in remote working conditions has become a society-wide issue (it is also intensely discussed in the case of distance learning). It is reasonable to assume that the approaches of employers could improve over time.
Large agglomerations tend to have business entities with a greater financial capacity that can be directed towards non-wage benefits for employees. Additionally, foreign capital may influence a different organizational culture that places more emphasis on taking care of employees during and immediately after a pandemic.
Employees of hotels, restaurants, and other catering and accommodation services believe that their employers did not provide them with adequate equipment and tools to enable them to work remotely. Such a response may be a consequence of the total lockdown that affected these industries. At that time, hotels and restaurants were completely closed, so employers saw no need to equip their employees with remote infrastructure.
Different approaches to employee support can be seen for the "company size" variable. Only employers with more than 500 employees offered their employees safety advice related to COVID-19. These results are very similar to the results of research on corporate social responsibility practices [45,[49][50][51], which showed that small and medium-sized enterprises are not interested in corporate social responsibility (CSR), mainly due to the need for additional costs or time. It can be assumed that these two premises became a destructive factor in this case.
From the perspective of the position, both lower-and higher-level managers were offered COVID-19 health safety advice by their employer.
Research shows that online health support and access to appropriate equipment and tools to enable remote work after a pandemic are unlikely to be needed.

Research Limitations
On the one hand, Ward's method is conservative and even monotonic, producing more or less the same large groups, but on the other hand, it is sensitive to outliers. Compared to other methods, Ward's approach ensures greater accuracy of the results and minimizes the variance between the elements. Hands and Everitt [43] showed that in a set of five grouping techniques, Ward's method performed better than other hierarchical methods. By running simulations on multiple datasets, Blashfield [52] came to similar conclusions.
The disadvantage of the hierarchical method is that once a merge or split is performed, it can never be undone. However, this kind of inflexibility is useful because since one does not have to worry about a combinatorial number of different options, it implies a lower computational cost.
Another limitation of using the hierarchical method is that erroneous decisions in the grouping process that have already been made cannot be corrected. The solution to this problem is to perform a careful analysis of the member associations with each hierarchical partition. It is also possible to integrate hierarchical agglomeration with other approaches by first using the hierarchical agglomeration algorithm to group elements into sets of microclusters and then performing macro-clustering on micro-clusters using another grouping method, such as iterative relocation [53].

Future Research Directions
The problem of forms of support for employee health and quality of work during and after a pandemic is a large field of research. It makes sense to expand research to extend to other industries and activities. Cross-national comparisons are also warranted. There is also a question that is worth looking at in the future: whether the time perspective will change the preferences related to forms of employee support for health and quality of work, i.e., how long the pandemic will act as a determinant in this respect.
