As a strategy to contain potentially infected people and prevent the virus from spreading further, businesses and schools will heavily rely on the internet to keep business running. From online learning to telecommuting, many aspects of our daily lives that used to involve face to face contact will be moved to cyberspace. This shift to internet-based work presents both advantages, challenges, and potentially a detriment to the education and business communities.

For some businesses, telecommuting can be a boon for their bottom line. Imagine a company that can run its entire operation staffed by workers who work from home. No need to lease large office spaces. No need for long commutes. Flexible hours and working in your pajamas (or anything you want to wear). With telecommuting, you can hire a geographically diverse group of employees without worrying about where to house them or relocate them.

In terms of education, online learning also comes with some advantages. For a long time, schools and colleges have resisted online instruction, and institutions that do have been regarded as inferior. However, with a rapidly spreading virus and a campus full of people in close contact, schools have no choice but to turn to online classes as an alternative, albeit temporary, solution. By letting students learn from home, colleges can allow more students to take the same class simultaneously, while students who missed lectures for any reason can make up with video streaming.

On the other hand, not everything can be solved by moving online. Businesses in personal services, retail, and food and beverage businesses will suffer under this crisis, as personal interaction is still an essential part of those industries. Although, I suspect delivery platforms such as Amazon and UberEats are likely to see a boom in business as people are confined to their homes.

Meanwhile, although some classes can be successfully taught online, specific disciplines are impossible to instruct through the internet. From lab work for chemistry to the arts, these classes must be conducted in person. The closing of campuses would also negatively impact students, who paid thousands of dollars to colleges for room and board. Worse, for many international scholars, campus closures might mean they have nowhere to go.

Through our student work experience program, the education authority provides over 9000 work experience placements for young people each year. Our program is designed to offer employment opportunities for students that will enrich their academic studies and help them gain valuable work-related skills thereby improving their chance of finding a good job after graduation. A placement does not need to be related to a particular field of study and so participants may even discover areas of work they have never considered before.All secondary and post-secondary school students in full-time education are eligible to apply for the program. Individual case managers will determine the minimum level of academic achievement required for each job. During an academic term, a student may work part-time. During the summer holidays a student may work full-time or part-time. The education authority is responsible for the recruitment of all students under the work experience program. Applicants apply in person to our office and we refer candidates to the appropriate department.Our internship program is designed specifically for post-secondary students, whether part-time or full-time. Students on the internship program are given an assignment related to their research area offering them the chance to use their academic knowledge in an actual work setting. The academic institution plays an important role in the placement of students under this program and they will determine the duration of a work assignment. These traditionally last four months but internship assignments may vary from 4 to 18 months. Students in this program normally work full-time.
