David has been Chief Operating Officer for over three years. He has been asked to ensure that home working is no longer occurring and that all employees are coming in to work. David considers that a lot of staff have worked very efficiently at home and he has continually suggested that this is not necessary. This has not been well received and he got into a very heated argument with the Chief Executive. David was told that if he didn't have the balls to carry out the task he should think about his future at the Bank. David has told Priti that he is going to resign. If David resigns could he succeed with a claim for unfair dismissal
