Explanation:
On March 11, 2020, the World Health Organization declared that COVID-19 was a global pandemic, indicating significant global spread of an infectious disease (World Health Organization, 2020). At that point, there were 118,000 confirmed cases of the coronavirus in 110 countries. China had been the first country with a widespread outbreak in January, and South Korea, Iran and Italy following in February with their own outbreaks. Soon, the virus was in all continents and over 177 countries, and as of this writing, the United States has the highest number of confirmed cases and, sadly, the most deaths. The virus was extremely contagious and led to death in the most vulnerable, particularly those older than 60 and those with underlying conditions. The most critical cases led to an overwhelming number being admitted into the intensive care units of hospitals, leading to a concern that the virus would overwhelm local health care systems. Today, in early May 2020, there have been nearly 250,000 deaths worldwide, with over 3,500,000 confirmed cases (Hopkins, 2020). The human toll is staggering, and experts are predicting a second wave in summer or fall.
As the deaths rose from the virus that had no known treatment or vaccine countries shut their borders, banned travel to other countries and began to issue orders for their citizens to stay at home, with no gatherings of more than 10 individuals. Schools and universities closed their physical locations and moved education online. Sporting events were canceled, airlines cut flights, tourism evaporated, restaurants, movie theaters and bars closed, theater productions canceled, manufacturing facilities, services, and retail stores closed. In some businesses and industries, employees have been able to work remotely from home, but in others, workers have been laid off, furloughed, or had their hours cut. The International Labor Organization (ILO) estimates that there was a 4.5% reduction in hours in the first quarter of 2020, and 10.5% reduction is expected in the second quarter (ILO, 2020a). The latter is equivalent to 305 million jobs (ILO, 2020a).
Globally, over 430 million enterprises are at risk of disruption, with about half of those in the wholesale and retail trades (ILO, 2020a). Much focus in the press has been on the impact in Europe and North America, but the effect on developing countries is even more critical. An example of the latter is the Bangladeshi ready-made-garment sector (Leitheiser et al., 2020), a global industry that depends on a supply chain of raw material from a few countries and produces those garments for retail stores throughout North America and Europe. But, in January 2020, raw material from China was delayed by the shutdown in China, creating delays and work stoppages in Bangladesh. By the time Bangladeshi factories had the material to make garments, in March, retailers in Europe and North American began to cancel orders or put them on hold, canceling or delaying payment. Factories shut down and workers were laid off without pay. Nearly a million people lost their jobs. Overall, since February 2020, the factories in Bangladesh have lost nearly 3 billion dollars in revenue. And, the retail stores that would have sold the garments have also closed. This demonstrates the ripple effect of the disruption of one industry that affects multiple countries and sets of workers, because consider that, in turn, there will be less raw material needed from China, and fewer workers needed there. One need only multiply this example by hundreds to consider the global impact of COVID-19 across the world of work.
