Being adept at a foreign language seems the easiest way for Koreans to make quick money at a part-time job because learning English has long been popular among locals hoping to lift their employment prospects.

According to Albamon.com, a part-time job listing site, the highest-paid part-time jobs are indeed in foreign language teaching. By contrast, clerking at convenience stores or fast food chains pays less than half what the teachers get.

The portal said foreign instruction positions paid an average 8,936 won ($8.90) an hour, according to an analysis of 112,621 jobs recently advertised on the site. Next most profitable were private tutors, at 7,783 won, followed by art and sports instructors at 6,895 won.

(The difference is that you don’t have to take your work home with you when you work in a restaurant or shop. I worked out my true hourly rate when teaching and it wouldn’t keep a squirrel in nuts.)
