(AHFE International, 2024) Amusan, Lekan; Aigbe, Fortune; Aigbavboa, Clinton; Idowu, Ayobami
The various industrial revolution from the first industrial revolution birthed water and steam-powered manufacturing facilities, the second industrial revolution birthed electrically powered mass production, the third industrial revolution led to the birthing of computers and Robots, while the fourth industrial revolution welcomed Cyber physical systems and the internet. The advent of computers and the internet has led to the use of social media platforms such as Facebook, Twitter, and Instagram, which can be used for work and for communication. The workers who will need these platforms will be those who are already employed, as well as those who need to be employed Hence, requisite skills (which could be both hard and soft) are required to use these platforms effectively. This study is based on the use of secondary data sources such as articles and journals using inductive and semantic approaches and thematic analysis. The study aims to promote the effective utilization of social media for work and communication through the Head, Hand, Heart Approach to Education and Training. The study reveals that the Head and Hand approach, which is cognitive learning and practical doing, provides the workers with the necessary hard skills to use social media. The Heart approach, which is affective learning, relational knowing, and emotional involvement, provides workers with the necessary soft skills to use social media for communication. The study contributes to scholarly discussions on workforce education and training in the digital era, as well as empirically contributes to the effective management of the workforce of the future.

Gig Regulation: A Future Guide for the Construction Industry
(MDPI, Basel, Switzerland, 2025) Amusan, Lekan; Aigbe, Fortune; Aigbavboa, Clinton; Aliu, John
Technology has led to the advent of digitally enabled workforces like the gig workforce, but a number of issues confront this workforce. This study aims to identify the various issues facing the gig workforce as well as the regulatory measures and regulatory interactions proposed to guide stakeholders in addressing these challenges. This study is a review, with the methodology primarily based on secondary sources of data collection like journals and articles. This study reveals that the construction industry is not immune to the use of the gig workforce, as it often performs project-based construction work, jobs requiring highly specialized skills and commodity service jobs. This study also reveals that the gig workforce is confronted with primarily gig economy-induced platform-based challenges, such as the new nature of work, i.e., exploitative, precarious, and dangerous labour. Furthermore, this study also reveals that these issues can be addressed primarily through regulatory means and regulatory interactions between proposed regulatory measures and existing labour laws, which could be by Coordination, Competition, etc. This aligns with SDG 8, i.e., Decent Work and Economic Growth, as concerns issues related to their benefits, and SDG 10, i.e., Reduced Inequalities, as concerns issues related to their employment relations. The implication of this study for construction stakeholders relates to the development of new regulations and providing a valuable tool for analysing regulatory landscapes and understanding the dynamics of regulatory change, which contributes to scholarly discussions on fair labour practices and the protection of gig workers and helps inform policymaking that will help attract, motivate, retain, and engage more gig workers in the construction industry, which will foster proper workforce management.
