Frontline workers are individuals who work directly with customers, clients, patients, or the general public in a variety of industries such as healthcare, retail, hospitality, and emergency services. These workers are often on the front lines of serving and interacting with individuals, and play a crucial role in providing essential services to the community. Research in this area may focus on understanding the experiences and challenges faced by frontline workers, their job satisfaction and well-being, their interactions with customers or clients, and strategies for supporting and improving their work conditions. This research is particularly relevant in the context of crises or emergencies, such as the COVID-19 pandemic, where frontline workers are essential for maintaining societal functioning and responding to urgent needs.
