Contrasting effects of leadership styles on public service motivation: the mediating role of basic psychological needs among Indian public sector officials

Abstract

PurposePublic service motivation (PSM), among actual and prospective employees in the public sector, lead to positive work outcomes. However, there is limited integration of PSM with existing motivational theories, especially self-determination theory (SDT). The impact of destructive leadership styles on PSM is also understudied. The study aims to fill the gap.Design/methodology/approachThe study used a cross-sectional survey of 693 public sector officials employed in Indian Railways to test the hypotheses. PLS-SEM was used for the analysis. The study found that fulfillment of basic psychological needs (BPN) at work leads to improved PSM while BPN partially mediates the positive/negative effect of constructive/destructive leadership styles like servant/autocratic leadership on employees' PSM.FindingsAutocratic/servant leadership was negatively/positively and significantly related to PSM and to all three BPN needs. Servant leadership was found to be positively and significantly related to all three BPN needs, while the BPN needs partially mediated the relationship between servant leadership and PSM.Research limitations/implicationsThe study identifies servant leadership as a driver of PSM and suggests that managers employed in public sector establishments should be trained to be less autocratic and more attuned to subordinates' needs. The baneful impact of autocratic leadership on employee PSM is highlighted. The cross-sectional nature of study makes it susceptible to common-method bias. The sample was limited to a single country. Future longitudinal and experimental studies based on samples drawn from multiple countries can yield more robust results.Originality/valueThe study advances the integration of PSM with SDT by identifying PSM with introjected motivation. It is also the first study to link destructive leadership styles with a reduction in employees' PSM. It identifies a counterintuitive, negative relationship between competence need satisfaction and PSM in the Indian public sector.

The Impact of Leaders on Motivating Human Resources in Organisations

“…Analysis of the impact of leadership on the performance of employees through motivation and achievement of job satisfaction has been presented in many studies (Semedo et al, 2022, Elifneh and Daniel, 2022, Nguyen et al, 2022, Zarei and Issahaka, 2022, Gao et al, 2022, Dash et al, 2022, Ashiq et al, 2023. Leaders are interested in attracting and retaining highly skilled and experienced employees to perform tasks aimed at achieving the strategic objectives and tactical objectives of the organization.…”

Job embeddedness and turnover intention in the public sector: the role of life satisfaction and ethical leadership

“…Another element expected to affect the link between JE and TI is EL. Leadership in the public sector plays a significant role because it involves interactions between leaders and followers (Hattab et al ., 2022; Dash et al ., 2022), and ethical leaders are expected to strengthen the web created to retain employees in the workplace. Ethical leaders are people with integrity, compassion and moral character, who support ethics and discuss this theme with their subordinates (Brown and Treviño, 2006).…”
