The labor ministry last month asked an advisory body to discuss possible revisions to the law governing the dispatch of temporary contract workers. The Hatoyama administration hopes to improve the stability of dispatch workers' employment situation, and plans to send a bill containing revisions to the Diet in March.

According to a ministry draft of the revision bill, the current temp system, which sees registered workers go without pay when there is no work to occupy them, will be banned in principle. Exceptions will be made for 26 fields of work that require specialized skills, such as interpreting. The draft proposes that the ban be phased in over a period of up to five years.

The draft also calls for dispatch on assignments lasting two months or less to be prohibited in principle, and for temp agencies to be obliged to make their commission margins public.
