PurposeThe literature on leadership is quite extensive; however, this study explains the impact of leadership styles on career success, career competence and career adaptability in the health sector. It explains the impact of servant leadership on career competence and career adaptability with a serial mediating impact of psychological safety and proactive behavior as well as self-efficacy and proactive behavior.Design/methodology/approachIt is a quantitative study, and it tested the suggested model in hospitals in Pakistan. The data were collected from 310 health practitioners from the hospitals, and it was analyzed with partial least square structural equation modeling.FindingsThe findings suggest that psychological safety and proactive behavior serially mediate the impact of servant leaders on career competence and career adaptability; hence, servant leadership tends to increase career competence and career adaptability of individuals. One more serial mediation has been tested with positive results between servant leadership and career competence and career adaptability.Originality/valueThe study takes a very well theoretically linked model which tests the serial mediating path of servant leadership to career competencies and career adaptability.

Purpose ‒ Considering the proclamations of trustworthiness within the Islamic financial system and the positive relationship between stock market reaction and earnings announcement of the trustworthy firm, this paper aims to empirically test the presence of trust in Sharīʿah-compliant listed firms in Pakistan. Design/Methodology/Approach ‒ The research question has been addressed by investigating firms listed on the Pakistan Stock Exchange (PSX) from 1 July 2019 to 30 June 2020. Event study method has been used by taking Abnormal Return Variance (ARV) and Abnormal Trading Volume (ATV) as proxies to measure the investors’ reaction following earnings announcements. Findings ‒ The results suggest that stock price variations around earnings announcements are negatively related to trustworthy firms compared to less-trusted firms (i.e., Sharīʿah non-compliant firms). For ATV, it was found that traders react to annual earnings announcements for both types of firms in a similar way. Originality/Value ‒ This research is an attempt to evaluate the Islamic financial system from its trustworthiness perspective. Sufficient literature has already documented that being trustworthy is obligatory for Sharīʿah-compliant firms. This study contributes to the literature by examining whether the market/investors trust such firms or not. Research Limitations/Implications ‒ This research is based on a single-country analysis with a research span of one year. Cross-country analysis with a broader time horizon may give further clarity. Practical Implications ‒ This paper has made a valuable contribution to the literature by providing the guideline on how investors’ reactions to Sharīʿah-compliant firms differ from their reactions to Sharīʿah non-compliant firms. It also indicates how religious elements may subdue other social factors such as trust. This paper has also explored the market reaction by assessing both the liquidity and volatility of the stock market in Pakistan.
