As Korean companies make the switch to the five-day workweek, increasing numbers of workers look forward not to a relaxing weekend but to a chance to make extra money on the side, a survey suggests.

A survey of jobseekers by Albating (www.albating.com), the part-time job site of Incruit recruitment consultants, shows the number of people looking for weekend work increased 96.9 percent in the first half from a year ago, and 59.4 percent of the number already had weekday jobs.

The number of part-time jobseekers surged 33.4 percent overall in the first half of the year compared to the same period of last year, before the five-day workweek was introduced for companies with over 1,000 employees.

Employed people in their 30s were most willing to get a weekend job, followed by those in their 40s and those in their 20s, possibly because the first two groups are more likely to need the money and face an insecure future, while workers in their 20s are more interested in their hobbies and leisure.
