Read the following scenario and then answer the following question. Aiden Fick, a 35-year-old pharmaceutical sales representative, was driving home from a business meeting one evening when a drunk truck driver ploughed into him. Aiden was badly injured but lucky to be alive. After more than a year of recovery and many surgeries, he is now confined to a wheelchair and has difficulty talking - his speech is barely audible. Because of the physical challenges he is facing daily, he can no longer perform his job. Management at the company he works for (Merck, Bayer and Roche) feel sorry for Aiden, but they need to appoint someone to take over his portfolio of clients and attract new clients in a very competitive business environment. How can the management of Merck, Bayer and Roche ensure that the potential dismissal of Aiden Fick is conducted fairly, considering his unique circumstances and physical limitations resulting from the accident? Identify the grounds on which Aiden could be dismissed
