John Li Has Worked as Manager of a Video Store

John Li has worked as manager of a video store for six years.Since the 7-Eleven store next door began renting movies for 97 cents,his business has fallen off drastically.Accordingly,the owner of the business told Li that,because the business had fallen on such hard times,he would take over managing and Li would have to take over the counter duties.The present counter clerk would be laid off.The owner also told Li that his wages would be reduced by 15 percent.When Li came to work the next day,he told the owner that he wouldn't accept the job working at the counter.The owner became angry and said,"If you don't like it,then you can leave! I don't have to put up with your insubordination one minute!" Li left and then sued the owner for unlawful dismissal.The owner argued that he had "just cause": economic slowdown and disobedience.Given the above facts,identify the true statement.
