The disruptive nature of unforeseen events (e.g. Covid-19) has a harsh impact on organizations’ stakeholders, including employees, society and the environment. However, these events pose tougher challenges for vulnerable and weaker workers, particularly in getting access to decent and productive employment. While catering to the changing needs of business, organizations also find it difficult to provide decent work for all and achieve their social bottom lines. This paper aims to understand what role HRD plays, especially Sustainable HRD (S-HRD), in facilitating access to decent work. Conceptual analysis of the literature revealed that S-HRD practices have the potential to promote all the dimensions of DW: employment creation, social protection, employees’ fundamental rights and social dialogue. This paper is an important stepping stone in the articulation of how S-HRD can help organizations to promote decent work. The perspectives presented in this study have potential implications for HRD practitioners in understanding the application and implementation of S-HRD practices. Furthermore, managers can also take note of specific S-HRD interventions from this paper to enable decent work in their organizations.","PeriodicalId":47369,"journal":{"name":"HUMAN RESOURCE DEVELOPMENT INTERNATIONAL","volume":"26 1","pages":"471 - 484"},"PeriodicalIF":6.3,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48323018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite increased attention on neuroscience discoveries and its methodologies in the social sciences, there is limited research among HRD scholars that incorporates neuroscience approaches. Relatedly, HRD practitioners and scholars often view reflection as a critical element for developing human resources and leaders. Yet, there is a dearth of research that focuses on the impact of reflection in the brain and the underlying neurocognitive mechanisms that support it. The purpose of this paper is to neurobiologically examine how individual or collective reflection impacts leaders’ frontal lobe brain activities during challenging situations, incorporating electroencephalography (EEG) as a method. The paper concludes with suggestions for future research and practical implications.","PeriodicalId":47369,"journal":{"name":"HUMAN RESOURCE DEVELOPMENT INTERNATIONAL","volume":"26 1","pages":"458 - 470"},"PeriodicalIF":6.3,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42868638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It establishes the rationale for LDO inclusion based on notable research contributions and differentiates the role and format of this event from conventional outdoor management development programmes through a focus on self-organized learning. The progression from individual learning to intra-group learning over the three days of the event is based on the interplay of action, theoretical inputs and self-evaluation. An emphasis is placed on purposeful conversation for shared learning, systems thinking and personal responsibility for seeking collaboration – essential elements in the life of real organizations. Individual reflective capability and group conversational processes for enhanced learning skills are stimulated in follow-up discussion after LDO with video input on key incidents. The learning achieved is generally observed to be beyond what conventional classroom activities can offer and sets in motion new thinking to consolidate and apply academic knowledge across the whole programme, providing a stimulus to career development.","PeriodicalId":47369,"journal":{"name":"HUMAN RESOURCE DEVELOPMENT INTERNATIONAL","volume":"26 1","pages":"341 - 352"},"PeriodicalIF":6.3,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44657467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although substantive literature exists on leadership during a crisis, less attention has been paid to regional leadership and leaders’ response during a crisis. The critical roles that regional organizations such as the Association of Southeast Asian Nations (ASEAN) and the European Union (EU) play in a crisis call for a better understanding of how these organizations and their leaders respond to regional crises. This paper provides a comparative insight into regional leaders’ crisis leadership and communication approaches in ASEAN and the EU during the COVID-19 pandemic in 2020. We describe the response timelines of the two regional organizations and highlight the significant roles of regional leaders in coordinating and implementing regional responses during a crisis, including providing consistent communication and collective leadership to facilitate cooperation, solidarity, and efforts towards recovery. We provide implications for HRD research and practice, specifically around the role of regional leaders in creating and implementing Regional HRD mechanisms in response to crises.","PeriodicalId":47369,"journal":{"name":"HUMAN RESOURCE DEVELOPMENT INTERNATIONAL","volume":"25 1","pages":"381 - 399"},"PeriodicalIF":6.3,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48758499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The overnight transformation in workplace operations caused drastic changes to the way organizations functioned; changes driven primarily by governments’ mandates to manage the public health impacts from the virus. Because of the nature of business, the tourism and hospitality industry has been one of the hardest hit , globally (Gursoy and Chi 2020). Worldwide, governments’ initiatives to flatten the infection rate curve, included lockdowns, closure of international borders, domestic and international flight and cruise travel restrictions, and the adoption of Standard Operating Procedures (SOPs) like the six-feet social distancing and mask wearing. With some degree of regional variation, the impacts of COVID-19 led to the closure of hospitality operations, resulting in serious repercussions for the industry (Sharma and Mahendru 2020). Since governments in both developed and developing countries recognize the hospitality economic and social major generator foreign exchange earnings, and employment creation 2005), addressing the impact of COVID-19 was an urgent concern for industry leaders. While a high degree of uncertainty and disruption had been caused by the pandemic at the broader level of hospitality operations, attention is also drawn to its impact on the workforce. By nature, this industry is heavily human resource intensive (Jayawardena Simply stated, it takes numerous employees at various levels to operate the industry (Baum Any in the industry creates impacts on the workforce. significant in international travels, millions of hospitality employees felt the effect of reduced work hours, furlough, or loss of employment.

The study highlights the importance of leadership actions during crisis events and the significance of the reflection-in-action approach. Formal and on-the-job training for CEOs and management should include components on leading through crises to prepare leaders to manage the organization into successful recovery. Leadership crisis training should provide the opportunity to hypothetically test various crisis management models to determine best case scenarios for handling different types of crises. Leaders can be trained to adopt certain competencies to lead effectively and to achieve organizational resilience through its strategies, employees, and other resources (Wooten and James 2008). The results from the crisis management model can be used in HRD practice to offer guidance on how the hotel industry can respond to, and recover from, the devastating effects of COVID-19.","PeriodicalId":47369,"journal":{"name":"HUMAN RESOURCE DEVELOPMENT INTERNATIONAL","volume":"25 1","pages":"298 - 320"},"PeriodicalIF":6.3,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43494727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The qualitative analysis revealed that leaders in both countries responded to the crisis by displaying certain behaviours and actions, including sharing power, finding ways to maintain productivity in a virtual work environment, prioritizing employee well-being, and using effective virtual communication strategies. This study provides evidence that, even with complex challenges and negative effects of the crisis, there is a window of opportunity to reform the workplace and to strengthen group cohesion and solidarity within public organizations.

In the cases we studied, leaders in USA adopted a consultative decision-making approach more often than their Indian counterparts. Moreover, group-based approach was evident only among leaders in USA. Leaders in both countries were creative and diligent in communicating, both to gather information as well as for dissemination. Leaders had to think out of the box to meet the needs of students and faculty, as well as the communities in their immediate areas. Resource identification and distribution, overcoming the digital divide between rural and urban areas, and the acquisition and appropriate allocation of safety equipment are just a few of the challenges addressed by the academic leaders.
