1. Introduction
In recent decades, Corporate Social Responsibility (CSR) has received the noteworthy attention of both academics and practitioners in business fields, especially on the features of environmental and ethical CSR [
1,
2]. Clarifying CSR is not a straightforward task; accordingly, it can be contingent upon perspective and point of view [
3]. It can theoretically intersect with several other ideas, such as citizenship, sustainability, and ethics. CSR nurtures the prominence of meaning in work and life to equal status as well as ecological integrity and financial sustainability. It likewise helps to recognize what essentially companies are doing with their profits and how they are affecting society. The mounting emphasis on CSR is not to focus on shareholder standpoint by maximization of profit, but to highlight the stakeholders’ perspective, including customers, government, suppliers, employees, and their prosperity [
4]. In the sense of this exploration, the focus is on the employees’ standpoint with regard to the environmental and ethical aspects of the business.
However, there is huge pressure for shareholder returns on the leaders of corporations, which can cause them to adopt a singular approach towards profit generation [
5]. In addition, with the challenge of escalating globalization and intensifying competition leading to ethical conflicts, managerial leaders are challenged with the responsibility of setting ethical standards that oversee the behaviors of their employees within their organizations [
6]. Huge business scandals of corporations such as Tyco international, Worldcon, and Enron, on the issue of profit and CSR, are some examples. Such conflicts might result in disregarding CSR if the proper leadership styles are not adopted. Companies’ habits of conducting business are the reflection of what the leaders determine as acceptable or not acceptable behavior in that business. In return, such ways of directing business have the potential to massively affect society either positively or negatively.
A significant number of scholars proclaim that there is an optimal level of CSR, which will simultaneously maximize profit and satisfy the demand for CSR emanating from various stakeholder groups [
7]. Leadership plays a vital role in order to determine the correct strategy for such optimal levels. According to Christensen et al. [
8], the approach of leadership can strengthen CSR in the sense that it suggests process models and explanatory mechanisms to CSR. Therefore, organizations should place comprehensive attention on selecting virtuous leaders, who will influence their employees positively into engaging in environmentally and ethically responsible actions. Targeting to advance in certain areas with an incompetent or inconsiderate leader towards CSR would be a mistaken starting point for further goals of development. The theories of transactional and transformational leadership have been previously called for research, since they deliberate a broader display of leadership components, as drivers of CSR practices. Transformational leadership has become the leading topic of interest among academics since it provides a significant and positive impact on the performance of organizations as well as the employees [
9].
Academics have likewise emphasized the link between leadership styles and CSR [
10,
11,
12], where various studies focused on transformational and transactional leadership [
13,
14]. Even though the dominating literature states a visible link between leadership and CSR, scholars’ findings on the specific styles of leadership inclined to be differing at times. Precisely, Ali et al. [
14] concluded that transformational leadership has a positive relationship with CSR in relation to media, employee, customer, and non-profit organizations. Whereas, according to Ho et al. [
15], transactional leadership enhances a corporation’s CSR practices while transformational leadership does not. Moreover, a substantial part of the literature explored either leadership or CSR as mediating factors while researching other outcomes such as organizational or job performance. For instance, Manzoor et al. [
16] concluded that CSR considerably mediates the relationship between transformational leadership and job performance.
Nonetheless, this research takes a more profound direction through numerous distinctive ways. Firstly, the focus is solely on environmental and ethical CSR which are two chief components of social responsibility, through keeping the employees’ perspective as the center of attention. There has been research on the direct link between leadership styles and environmental CSR [
17]. However, the differences are still existent with the addition of ethical CSR, location of the research, and unrelated moderating variables. In addition, employees’ years of employment in their current company is considered as a crucial factor, since it is directly connected with the time spent under their companies’ norms. It has been suggested that increases in length of employment are associated with more favorable supervisor ratings [
18], since they can lead to an enhanced understanding between the leaders and the employees. Thus, it is added as a moderating factor between leadership styles and CSR.
Even though previous research has been conducted in different countries and industries [
19,
20], not many have been carried out within the United Kingdom (UK) framework, especially in the financial services sector, which is an industry where an excessive singular approach towards profit generation is anticipated. The United Kingdom has a stable economy, with a growth rate between 1.3–2.3% in each of the past five years [
21]. Several vital details assist to comprehend the importance of the financial services sector in the UK. The financial services sector accounted for 7% of the UK’s economy in 2018 with a contribution of GBP 132 billion, which is the seventh-largest share within the Organization for Economic Cooperation and Development (OECD) countries [
22]. In addition, the UK’s banking sector assets (USD 10.8TRN) are the largest in Europe and its global net exports of financial services (USD 88BN) are the largest in the world [
23].
Within the context of this research, the financial services sector in the UK is deliberated to be central to explore the CSR concept, since this sector has been faced with complications such as low disclosure levels of CSR reports of businesses operating in the financial services sector of the UK, as well as negative social impact due to periodically massive restructuring and redundancies in employment, where the UK based workforces of banks like Citigroup and Royal Bank of Scotland were made redundant [
24]. However, Day and Woodward [
25] highlighted that such low disclosure is related to size, as the likelihood of compliance rises with bigger companies, which might indicate a resource issue. On the contrary, there are substantial actions towards CSR as well, with the application of the green finance concept, where the funding of investors is directed towards making improvement on acknowledged environmental goals, as 26 investment companies and unit trusts play an active role in this process, including giant corporations such as Parvest and Allianz [
26].
Inclusion of the leadership styles is believed to be imperative to this research, after perceiving such increasing action towards CSR in the financial services industry. However, the previous research in the UK financial services sector has linked leadership styles with organizational performance and organizational culture [
27], or used differing leadership styles with regard to CSR, such as visionary and servant leadership [
28]. Consequently, in the financial services sector of UK, there is a lack of research carried out to examine the effect of transactional and transformational leadership styles on environmental and ethical CSR, with the moderating effect of employees’ years of employment in their respective company. In consequence, this research intends to fill the gap. This research can present outcomes that will potentially present clear pathways to the leaders of the financial services companies to consider specific styles of leadership that can result in socially responsible actions, which benefits the whole society. Moreover, the findings can be the starting point of more profound research in the area of leadership and CSR in the financial services sector.
The remaining parts of this article are prepared in the following manner. The subsequent section provides the literature review, which leads to hypotheses development. After
Section 2,
Section 3 delivers the clarification of the methodology in detail, which includes the data collection method and procedure, sample, as well as the method of data analysis.
Section 4 explains the data with its analysis and findings, and then the study is settled with discussion and conclusion presented in
Section 5.
4. Data Results and Analysis
The data were analyzed by using the Statistical Package for Social Sciences (SPSS) for Windows 25.0 and Analysis of Moment Structures (AMOS) 23.0 programs. Reliability assessment was conducted in order to test the dependability of the questionnaire, as well as applying Confirmatory Factor Analysis through AMOS to test the validity. After that, Structural Equation Modelling (SEM) was applied to perceive the accountability of the hypotheses. SEM was perceived to be an ideal approach for further analysis, as it enables testing of a set of hypotheses simultaneously while accounting for measurement error [
104,
105].
In addition, it was also tested whether the data were normally distributed, which can be investigated through a Quantile-Quantile Plot drawing [
106]. The normal distribution of the data is dependent upon the skewness and kurtosis values being around ±3 [
107]. The outlier values increase the error variance of values and, thus, they affect the power of statistical tests. It was checked whether there were outlier values in the data set for such a reason. Since the applied questionnaire was found to be normally distributed, parametric tests were chosen to be applied for statistical assessments. A
T-Test was used to compare two independent groups of quantitative data, and Analysis of Variance (ANOVA) was applied to test more than two groups.
The correlation analysis shown in
Table 1 was used in order to test the relationship between the variables. As a result, it was comprehended that Transformational Leadership positively correlates with Transactional Leadership (r = 0.764,
p < 0.05), Environmental CSR (r = 0.187,
p < 0.05), and Ethical CSR (r = 0.552,
p < 0.05). Likewise, Transactional Leadership positively correlated with Environmental CSR (r = 0.134,
p < 0.05) and Ethical CSR (r = 0.549,
p < 0.05). There was a positively correlated relationship between Environmental CSR and Ethical CSR as well (r = 0.253,
p < 0.05).
Besides, the following
Figure 2 presents the relationship between the independent variables and the dependent variables, which will be analyzed in detail on the subsequent parts of this section.
The measurement model’s reliability was established by utilizing Cronbach’s Alpha. The values at the level of 0.60 and above regarding Cronbach Alpha indicate that the measurement is reliable and has high convergent validity [
108]. The Cronbach’s Alpha calculations showed 0.836 for Transformational Leadership, 0.738 for Transactional Leadership, 0.679 for Environmental CSR, and 0.761 for Ethical CSR, which are all reliable outcomes. In addition, entire correlations between the variables exhibited item factor weights above 0.40, which indicates valid relationships between the variables. These results can be observed in detail from the following
Table 2.
Moving to the next measure, the Confirmatory Factor Analysis shows that the Structural Equation Modelling results of the model are meaningful at the level of
p = 0.000. The analysis led to the exclusion of one item (TSC5) from the measurement due to the low factor level. The remaining factors were found to be correlated with the model. While improving the model, the variables that lower the fit were determined, and new covariance was formed for high covariance values on residual values. The newly formed index calculations are shown in the following
Table 3 where the optimal value levels are reached.
The following part of this section will examine the relationship between the variables in detail. To begin with, the relationship between the independent variable of Transformational Leadership and the dependent variable of Environmental CSR was studied, with the addition of employees’ years of employment in their current company, which was the moderating variable. The appraisals revealed that Transformational Leadership has a positive and statistically meaningful effect on Environmental CSR (
p < 0.05), where 1 unit of increase in Transformational Leadership leads to 0.255 units of increase in Environmental CSR (β = 0.255). This relationship is an acceptable level of fit between the variables. On the other hand, the results showed that the moderating variable of years of employment has no moderating effect on the relationship between Transformational Leadership and Environmental CSR (
p > 0.05). These results are shown in the following
Figure 3 and
Table 4.
The next measurement investigated the relationship between the independent variable of Transactional Leadership and the dependent variable of Environmental CSR, where the moderating variable of years of employment was unchanged. As a result, Transactional Leadership has a positive and statistically meaningful (
p < 0.05) effect on Environmental CSR, where 1 unit of increase leads to a-0.187 increase, respectively (β = 0.187), which is an acceptable measure of the fit level. Employees’ years of employment in their current companies did not have a significant moderating effect on the relationship between Transactional Leadership and Environmental CSR as well (
p > 0.05). These measurements are shown in the following
Figure 4 and
Table 5.
The next feature is on the relationship between the independent variable of Transformational Leadership and the dependent variable of Ethical CSR, where the moderator is stable. Calculations displayed a positive and statistically meaningful (
p < 0.05) relationship between the variables, where 1 unit of increase in Transformational Leadership leads to a 0.688-unit increase in Ethical CSR (β = 0.688), which is a satisfactory degree. In addition, years of employment in current the company were measured to have a moderating effect on the relationship between Transformational Leadership and Ethical CSR (
p < 0.05). The results are presented fully in the following
Figure 5 and
Table 6.
After that, the relationship between the independent variable of Transactional Leadership and the dependent variable of Ethical CSR was investigated, with an unchanged moderating variable of years of employment. There was a noteworthy positive relationship (
p < 0.05) between the variables, where 1 unit of increase in Transactional Leadership led to a 0.745-unit increase in Ethical CSR (β = 0.745). On the other hand, the moderating variable was not established to have a moderating effect on the relationship between the variables (
p > 0.05). The results are shown in the following
Figure 6 and
