About one out of five salaried workers has a second job, according to a recent survey of 1,074 salaried workers released by jobs website Incruit on Wednesday. The proportion of moonlighters has been rising steadily to 18.2 percent from 12.9 percent in 2008 and 15.5 percent last year.
When asked why they are working two jobs, most respondents or 49.2 percent said extra income, followed by self-improvement (12.3 percent), a preparatory step for opening their own business (11.3 percent), provision for retirement (10.3 percent), and hobby or recreational activities (7.2 percent).
Some 35.9 percent said the income from their second job amounts to between 11 and 20 percent of that from their main job, while 8.2 percent said it is as high as between 51 and 60 percent.
"Rather than jumping into a second job to make extra money quickly, prospective moonlighters should take a cautious approach, taking into consideration their heath, biorhythm, interests and skills," Incruit advised.
