How does employee hidden mental illness manifest adversely in workplaces?

An employee hidden mental illness has become the most prevalent illness found in western societies today. It has widely emerged within many workplace organisations and surprisingly remains largest among the medical and health sciences fields. According to De Lorenzo and Mirella (2013), hidden mental illnesses effect between 17% and 20% of employees in a given twelve month period. The most common hidden mental illnesses are depression and anxiety, depression effecting 4% and anxiety 14% of employees in a twelve month period. The socio-economic impact of mental illness within the workplace is frightening, the loss of productivity and costs have already caused major damage, and serious consequences for the future when depression and anxiety within the workplace increase. Mental illnesses within the workplace can be worsened if the employee has poor self-management of their illness, which includes inconsistent medication use, and social factors such as low social support, discussed by Munir, Yarker, Haslam, Long, Leka, Griffiths and Cox (2007). Mental illnesses are not treated like physical illnesses by society. They are pushed aside and not seen as a real disease that impairs peoples abilities because it is an invisible illness. Stigma of mental illnesses within the workplace is a major reason why employees choose to conceal their issues. Employees can feel labelled, less capable and treated differently by all co-workers and management, constantly under pressure to achieve goals and perform like the rest. Another reason of non-disclosure of a mental illness is the fear of career damage or loss. An employee can feel threatened by others knowledge of their illness and in turn would rather keep it hidden. To them this avoids the problem, but has a negative impact to the company. Across many
