Mental health problems are among the most important contributors to the global burden of disease and disability. Of the ten leading causes of disability worldwide, five are psychiatric conditions: unipolar depression, alcohol use, bipolar affective disorder (manic depression), schizophrenia and obsessive-compulsive disorder.1
The burden of mental disorders on health and productivity throughout the world has long been profoundly underestimated.2 The impact of mental health problems in the workplace has serious consequences not only for the individuals whose lives are influenced either directly or indirectly, but also for enterprise productivity. Mental health problems strongly influence employee performance, rates of illnesses, absenteeism, accidents, and staff turnover.
The workplace is an appropriate environment in which to educate and raise individuals' awareness about mental health problems. For example, encouragement to promote good mental health practices, provide tools for recognition and early identification of the symptoms of problems, and establish links with local mental health services for referral and treatment can be offered. The need to demystify the topic and lift the taboos about the presence of mental health problems in the workplace while educating the working population regarding early recognition and treatment will benefit employers in terms of higher productivity and reduction in direct and in-direct costs. However, it must be recognised that some mental health problems need specific clinical care and monitoring, as well as special considerations for the integration or re-integration of the individual into the workforce.
Why should the ILO be involved?
Mental illness constitutes one of the world's most critical and social health problems. It affects more human lives and wastes more human resources than any other disabling condition.3 The ILO's activities promote the inclusion of persons with physical, psychiatric and intellectual disabilities into mainstream training and employment structures.
The ILO's primary goals regarding disability are to prepare and empower people with disabilities to pursue their employment goals and facilitate access to work and job opportunities in open labour markets, while sensitising policy makers, trade unions and employers to these issues. The ILO's mandate on disability issues is specified in the ILO Convention 159 (1983) on vocational rehabilitation and employment. No. 159 defines a disabled person as an individual whose prospects of securing, retaining, and advancing in suitable employment are substantially reduced as a result of a duly recognised physical or mental impairment. The Convention established the principle of equal treatment and employment for workers with disabilities.
Most recently, the ILO has recognised the need to promote increased investment in human resource development, which can help support employment productivity and growth. This focus pays particular attention to the human resource needs of vulnerable groups, which include individu-
