Fewer hours on the main job, perhaps, but at the same time, many people are looking for more work... in things they find fulfilling.
It's part of the so-called "gig economy."
Oh Soo-young takes a closer look.
Thirty-two year old Moon Hoon is a sales employee by day.
But from 6 PM onwards, he is a skateboarding instructor.
Using an online platform to match teachers with students,... Moon makes anywhere between 20 and one-hundred percent of his monthly wage from teaching skateboarding.
And he also gets to share his passion with students from a wide range of ages and backgrounds.
"Teaching others and sharing with them what I love gives me a real sense of accomplishment. And the fact that it's good exercise helps me feel refreshed, rather than wear me out after work. Doing my desk job and teaching skateboarding really gives me the best of both worlds."
"Teaching how to skateboard is just one example of how Koreans in their 20s and 30s are increasingly taking on side jobs after work and not just for the extra pay check but also to pursue their interests and share their skills with others."
College instructor Sae-jin Kang teaches leadership at a university in Incheon but during his free time, he works as a professional translator.
Given the long summer and winter holidays in the academic year,... it's a way of stabilising his income through meaningful tasks.
"Being able to work on different kinds of projects or being able to see different movies or dramas that I've translated on... I find that very fulfilling."
Kang has been using an online platform where clients can send a request for professional services in diverse areas: from marketing and programming solutions to make-up and drawing classes.
"9 out of 10 experts on our platform are working second jobs. In the past, people weren't so open about taking side jobs but now, with online platforms such as ours, there is an active marketplace where you can easily find work that you can do."
South Korea's 52-hour work week policy which went into effect last year,... has also increased the number of people seeking side-jobs, according to Park.
The trend is also seen as part of the global shift towards the gig economy,... as work conditions become more fluid and flexible in the era of the Fourth Industrial Revolution.
