This paper aims to provide a critical reflection on the impact of the gig economy on the hospitality workforce. The impact of the gig economy on hospitality workforce management is explored, with the paper delving into both theoretical insights and practical implications.

This paper offers reflections on the emerging trend of the gig economy and its impacts on the hospitality workforce, based on evidence collected from the selected literature, industry report and authors’ personal reflections. A micro-meso-macro analytical framework was also applied to assist authors in building the arguments and propositions.

The findings not only revealed the impacts of the gig economy on the hospitality workforce at micro-meso-macro levels but also underscored its close relationships with various concepts in the hospitality management literature. Both future research directions and practical implications are provided.

Amid the gig economy’s transformative influence, stakeholders must continually innovate for an empowering and secure work environment. A holistic approach is necessary to establish a harmonious gig ecosystem, ensuring fair treatment, benefits and protection for workers while fostering growth and well-being.

Throughout the paper, a critical reflection on the impact of the gig economy on the hospitality workforce is presented, along with suggestions for coping with current labor issues in hospitality and tourism. Future research directions are outlined.

The paper aims to study the effect of sintering temperature on the microstructure, shear strength and ratcheting fatigue life of nanosilver sintered lap shear joint. In addition, the Gerber model is used to predict the ratcheting fatigue lives of nanosilver sintered lap shear joints at different sintering temperatures.

In this paper, the nanosilver sintered lap shear joints were prepared at three sintering temperatures of 250 °C, 280 °C and 310 °C. The bonding quality was characterized by scanning electron microscopy, X-ray diffraction, transmission electron microscope and shear tests, and the long-term reliability was studied by conducting ratcheting fatigue tests. In addition, three modified models based on Basquin equation were used to predict the ratcheting fatigue life of nanosilver sintered lap shear joint and their accuracies were evaluated.

When the sintering temperature is 250°C, the nanosilver sintered lap shear joint shows the porosity of 22.9 ± 1.6 %, and the shear strength of 22.3 ± 2.4 MPa. Raising the sintering temperature enhances silver crystallite size, strengthens sintering necks, thus improves shear strength and ratcheting fatigue life in joints. In addition, the ratcheting fatigue lives of the joints sintered at different temperatures are effectively predicted by three equivalent force models, and the Gerber model shows the highest life prediction accuracy.

The sintered silver bondline is suffering a complex stress state. The study only takes the shear stress into consideration. The tensile stress and the combination of shear stress and tensile stress can to be considered in the future study.

The paper provides the experimental and theoretical support for robust bonding and long-term reliability of sintered silver structure.

The introduced model can predict the ratcheting fatigue lives of the joints sintered at different temperatures, which shows a potential in engineering applications.

The study revealed the relationship between the sintering temperature and the microstructure, the shear strength and the ratcheting fatigue life of the joint. In addition, the Gerber model can predict the ratcheting fatigue life accurately at different sintering temperatures.
