World Essential Workers Day is observed worldwide every March 15 to honor essential workers who provide vital services to the health and welfare of the population. This day was created to highlight the often underappreciated and underpaid contributions of these workers, who include those in health and social care, education, public safety, and various other sectors. The origins of the day are somewhat unclear, with claims that it was initiated by a nine-year-old girl from Texas or a nurse seeking to recognize the efforts of essential workers during the COVID-19 pandemic. The date was chosen because it marks the day in 2020 when COVID-19 cases in the U.S. surpassed 3,000. Celebrations typically involve thanking essential workers in the community, donating to local charities, and sharing messages on social media using hashtags like #WorldEssentialWorkersDay.
