With the bill to overhaul regulations on the use of temporary workers poised to clear the Diet this week, thousands of temps dispatched from staffing agencies worry they may lose their jobs in three years after the change takes effect.

Observers say those most affected by the revision of the worker dispatch law will be the temps engaged in 26 jobs designated as requiring specialized skills, including translators, software developers, interior designers and secretaries.

The current law puts a three-year limit on the use of temps to perform the same work, but the 26 jobs are exempt from the time limit.
