Part-time and contract workers in the manufacturing sector get less training than their permanent, full-time colleagues, raising concern that young people may not be gaining enough skills, according to a government report.

While 59.8 percent of regular employees get opportunities to train for other types of jobs, only 20.2 percent of part-time and contract workers are given the same chance, the white paper says, citing the results of a Health, Labor and Welfare Ministry survey.

As there is a growing trend of diverse working styles, particularly among young people, manufacturers are urged to make their part-time and temporary workers permanent, the paper says.
