General opinion is that a side job is one that supports the main income of an individual, often times perceived as something that brings little money to add to what you make from your day job. If Mr X earns better from a side job when compared to the income from his career option, does the side job still qualify to be called a side job?
The Side Job is also known as a Sales Associate or a Product Promoter, depending on the service industry. Of course, in the context of covid 19, finding a side job to earn extra income to cover living costs is very difficult during a pandemic accompanied by inflation. In fact, during the covid pandemic, people become more diligent and hardworking. Lol, I think it's a luxury to spend some time and earn a big income from a side job. However, even better if it is possible in many cases.
