The figures support the western prejudice that the Japanese are all working without play. Trying to force workers away from their desks and machines, the government said last April that the country should cut down from its 2,100 hours average work year to 1,899 hours and a five-day by 1992. Beginning in February, banks and offices two Saturdays a month. The government hopes that others will follow that practice. But some persuasion will be needed. Small companies are very angry about it and they fear competitions may not cut hour. The unions are no happier: they have even advertised in newspapers arguing their case against the foreign pressure that is forcing leisure upon them. They say shorter hours are a disguised pay cut.
