Eased regulations on the dispatch of workers and corporate cost-cutting efforts have worsened income gaps, the Health, Labor and Welfare Ministry said in an annual labor report Tuesday.
Further aggravating the problem is the opening of more fields for which workers can be dispatched, resulting in a rise in nonregular workers, including part-timers, seasonal and temporary staff, the 2010 White Paper on the Labor Economy says.
Long, stable employment is an effective way to achieve economic growth, the report says, noting the importance of developing human resources in terms of enhancing the ability to add value to goods and services.
