If we understand ethics in the work place as a continuous process, i.e. not merely something that is used as part of a company's social responsibility measurements, and with Kaizen improvement processes then the link is obvious. Ethics seeks to improve the moral conduct of individuals as such it should be intigral to Kaizen since one could ask if any organization has actually improved if it did not have sustainability in mind from the outset...if your employees are not schooled in ethics then at least in terms of human resources none of the Kaizen initiatives will be sustained in the long run...so 'true' improvement or Kaizen is only possible in the context of ethics since unethical conduct will counter any long term improvement initiatives if unaddressed. Hope this helps... Have a flew so could sound a bit muddled...
