The Japs are a weird bunch and can't easily be forgiven for their actions up to the end of WW2. They had to be stopped , same applies to the Germans. Stopping them meant going lower with our own standards and actions than would normally be acceptable. But they both HAD to be stopped or many of us would not be here now.
Back to the factory dispute, if the management are going back on monies promised and set in employment contracts then the workers have a valid case for dispute, if on the other hand this is simply an effort by the employees to gain more renumedeation than was promised, based on a good year for the company then bollix to them.
