Since the onset of the COVID-19 pandemic, we have faced many changes in our lives. The most pronounced change in working environments is that telecommuting has become routine. Twitter said its employees started telecommuting in early March this year, followed by U.S. global companies, including Microsoft, Google, and Amazon. Not only global companies but also Korean companies such as Naver and Kakao have followed the trend, but there are still many companies that do not telecommute. As telecommuting has been becoming more common, it should be further expanded even after the COVID-19, considering that it has advantages in terms of economy and environment for employees.

  First, telecommuting has excellent cost savings. Employees work from home, so they can reduce commuting time and costs. According to the Bloomberg, Upwork economist Adam Ozimek said American workers, in total, saved about $411 million a day when commuting by car based on the value of commuting time estimated at $12.50 per hour. Not only employees, but employers can also reduce costs for their business. In particular, companies in large cities can increase their net profits by reducing various costs such as office rent, monthly utility bills, and other business operating costs. Companies based in Silicon Valley, which boasts some of the highest rent in the U.S., are predicted to save cost a lot. The Wall Street Journal reported that office rent prices for San Francisco, where Silicon Valley is located, fell 4 % from late March to late September this year. Adam Ozimek in Upwork also said Americans have saved about $758 million a day since March this year from telecommuting due to the COVID-19 crisis, saving a total of about $91 billion. Second, telecommuting also has a positive effect on the environment. Telecommuting will reduce overall energy consumption, including electricity consumption in offices. Also, it can decrease the number of vehicles for commuting, which will reduce car emissions. "A New World of Remote Work," a report from Citi GPS, analyzed that if 52% of U.S. workers worked just 1 day in a week from home, CO2 reductions could drop 20 million tons annually, a 2.5% decrease and the equivalent of taking 4.3 million cars off the road. These will bring about very positive changes in serious environmental problems caused by global warming, such as floods and typhoons, which the world continues to face.

  Facebook CEO Mark Zuckerberg implied that telecommuting would be the New Normal, saying that half of all employees of Facebook will telecommute within 10 years. This is positive in that telecommuting is a key change in the post-Corona era and has the benefits of cost savings and eco-friendly aspects. As many global companies such as Twitter and Google have been implementing it, and companies that still do not work from home must also follow the trend and adopt telecommuting with its many advantages.
