Is this a sign of things to come, after all the Japanese economy has seen sagging consumption for years with a two tier economy with full time workers and parttime workers with no benefits. The parttime labor force increased from 4.13 to 4.79 million according to the Labor Department and its the highest since 1993. Now people are doing this not by choice but for economic reasons. And employers like Kroger are doing this so that they can hire more parttimers with no benefits and pay benefits to fewer employees. There are also computerized scheduling systems for parttimers that are becoming popular with retail stores that use a lot of partimers.
