Thirty-seven percent of temporary workers in Japan want to become permanent employees mainly because their current wages are low, according to a survey released recently by a temporary workers' association.

The survey, conducted by the Temporary Work Services Association of Japan, also showed that about 69 percent of respondents have contracts with their employers for less than six months and 87 percent have contracts lasting less than a year.

About 40 percent of the respondents wishing to become regular employees are in their 30s and 40s and tend to spend a lot of money on child and elderly care.
