During the course of the day, you receive the following complaints: (1) a complaint from employee Steve that alleges workplace harassment; (2) a complaint from customer Betty that alleges she was swindled into buying a very expensive policy covering injuries to her poodle; (3) a complaint from customer Larry that alleges the employee that he spoke with on the phone wasn't knowledgeable or licensed to sell the Surplus Lines policy that he purchased; (4) a complaint from Henry alleging that he was passed up for a promotion because of his age. How would you handle the various complaints?
