Reasons for Workplace Mental Illness Disclosure and Non-Disclosure in Japan ()
1. Introduction
In fiscal year 2012 in Japan, the number of people with disabilities employed at private companies reached a record high of 382,363 with the employment of people with mental disabilities showing a considerable increase of 27.8% over the previous year [1] . The Handicapped Person’s Employment Promotion Law (revised), enacted on June 19, 2013, primarily mandates that people with mental disabilities are added to the calculation bases of the employment rate for people with disabilities. The employment of people with mental illness in Japan is expected to continue to increase in the future. When people with mental illness choose normal employment, rather than employment through handicapped hiring quotas, some choose to disclose their illness, and others do not. What accounts for this difference? It seems reasonable to assume that those who disclose their illness want their work to proceed smoothly and request their employers to show consideration for their conditions, whereas those who do not disclose their illness want to avoid the low wages and poor working conditions associated with the stigma of mental illness.
2. Literature Review
Mental disorders are a significant cause of disability and loss of workplace productivity [2] . The number of people with mental disorders leaving vocational facilities and seeking employment in the ordinary workplace is much higher than the numbers of people with cognitive impairments or physical disabilities [3] . Fear of discrimination and legal, practical, and moral pressures have been shown to contribute to the tension between workplace disclosure and non-disclosure of a mental illness [4] . Additionally, people with mental disorders have commonly suffered from stigma following the disclosure of their illness [5] . Past work has indicated that anticipated discrimination by employers also presents a barrier to seeking mental health care [6] . People with mental disorders might actively reject the opportunity to work or stop looking for work in anticipation of prejudice toward them. This would indicate that users of mental health services face difficulties in deciding whether to disclose a mental health problem to an employer [7] . The present study investigated workplace mental illness disclosure, which had not yet been explored in Japan.
3. Study Aim
In this study, I conducted a questionnaire survey among people with mental illness with a history of employment to investigate their experiences of disease disclosure. The hope is that the results will help to create guidelines for support workers to manage the unavoidable problems associated with illness disclosure when providing career support to people with mental illness. The results are also expected to provide evidence that will benefit companies and society in general by contributing to building a society where people with mental illness can work without the need to hide their illness.
4. Methods
4.1. Participants
Participants were 69 patients with mental illness with an employment history who were inpatients in an open ward of psychiatric hospital A, outpatients of the hospital’s clinic, or users of the hospital’s day care center. Participant selection was implemented by the administrator of each facility, and participants who provided informed consent were enrolled in the study. The mental condition of all participants was stable because of continued regular medication, and none had problems with language, literacy, or thinking relevant to answering the study questionnaire.
4.2. Questionnaire Survey
In the questionnaire, patients wrote answers to three open-ended questions concerning 1) the reasons for disclosing or not disclosing their illness to their employer at the time of hiring, 2) the reasons for disclosing or not disclosing their illness to their supervisor and coworkers while they were on the job, and 3) requests for their employer to enable them to do their job smoothly.
4.3. Data Analysis
The data analysis was conducted using a method similar to that used by Indratula et al. [8] . Conventional content analysis, in which categories are directly extracted from textual data, was used to identify categories and themes in the data. Words and sentences expressing central meaning units were identified, and data were systematically condensed without changing the original meaning. Meaning units were labeled with codes, which were then sorted into categories and subcategories according to the similarities and differences between them. Iterative analysis was performed on the whole texts, codes, and categories. An interpretation of the underlying meaning that permeated the categories was formulated into themes.
4.4. Ethical Considerations
This study was conducted with the approval of the Ethics Review Board of Tohoku University Medical Science Postgraduate School and the participating hospital. All participants provided informed consent after receiving verbal and written explanations of the study, including the assurance that their participation would be kept confidential, that they could withdraw from the study at any time, and that all data would be handled anonymously and used for research purposes only.
5. Results
5.1. Participants’ Demographic Characteristics
The largest percentage of participants (36.2%) were in their 40s, and 75.4% were men. In terms of educational background, the largest group consisted of high school graduates (40.6%). Almost half of the participants were diagnosed with schizophrenia, and 76.8% of all participants had been hospitalized in a psychiatric hospital. Across different types of workplaces, 63.8% worked as regular employees, and 23.2%were part-time employees. The most frequently reported employment sector was the service industry (36.2%). Most participants (66.0%) did not disclose their illness to their employer at the time of hiring, and most did not disclose their illness to their supervisor while they were on the job (58.0%). Additionally, 42.0% of the participants recounted experiences of being treated differently by other people in the workplace (Table 1).
5.2. Disclosure and Non-Disclosure to the Employer during Hiring
Based the analysis of the data collected, I extracted four categories of reasons for non-disclosure at the time of hiring: anxiety about not being hired, anxiety about unfavorable treatment, lack of awareness of illness, and not feeling the need to disclose (Table 2).
I extracted two categories of reasons for disclosure at the time of hiring: disclosure to continue working and disclosure by other people (Table 3).
5.3. Disclosure and Non-Disclosure to the Supervisor While on the Job
I extracted seven categories of reasons for non-disclosure to supervisors: anxiety about dismissal, anxiety about stigma, anxiety about unfavorable treatment, not feeling the need to disclose, anxiety about violation of privacy, lack of awareness of illness, and no chance to talk (Table 4).
I extracted four categories of reasons for disclosure to supervisors: disclosure out of necessity, desire to be understood, disclosure to continue working, and disclosure by other people (Table 5).
5.4. Disclosure and Non-Disclosure to Coworkers While on the Job
I extracted eight categories of reasons for non-disclosure to coworkers: anxiety about stigma, potential obstacles at work if disclosed, anxiety about dismissal, lack of awareness of illness, consideration of human relationships, not feeling the need to disclose, anxiety about violation of privacy, and no chance to talk (Table 6).
I extracted three categories for disclosure to coworkers: desire to be understood, disclosure by other people, and disclosure to continue working (Table 7).
5.5. Requests for Employers
I extracted five categories of requests for employers: education, measures taken to cope with stigma, improved treatment, consideration for the illness, and readiness to work (Table 8).
6. Discussion
6.1. Anxiety about Dismissal, Not Being Hired, and Unfavorable Treatment
Disclosure of illness is a major problem for people with mental disorders [7] . The finding of the present study that should be emphasized is that anxiety about dismissal, not being hired, and anxiety about unfavorable treatment were common factors underlying the reasons why people with mental illness do not disclose their illness to

their employer or supervisor at the time of hiring or while on the job. Many studies in and outside of Japan have reported that 80% - 90% of people with mental illness are unemployed [9] -[13] . In their literature review, Laxman et al. [14] revealed that, in North America, the careers of people with borderline personality disorder were disrupted by dismissals, delayed or withheld promotions, demotions, or other events. Also, in an interview study of bipolar disorder patients, several respondents reported dismissals, delayed or withheld promotions, or demotions after they disclosed their disability [15] . Likewise, I expected that the participants in this survey would not disclose their illness owing to the prospect of such disadvantages. In other words, people with mental illness anticipate being socially alienated at the time of hiring or while on the job.
6.2. Anxiety about Stigma
I would also like to call special attention to anxiety about stigma, which was one of the reasons for non-disclosure to a supervisor or coworkers while on the job. Stigma is defined as a majority group in society making a negative evaluation of a minority group [16] [17] . People with mental illness generally internalize abusive or discriminatory societal attitudes. The lower they believe they are being evaluated, the more they fear interaction with others, and they defend themselves by hiding their illness, withdrawing from the community, or anticipating discrimination by refusing to be around others [18] . Angermeye and Matschinger [19] recognized the stigma felt by people with mental illness as an obstacle to creating a society where both handicapped and non-handicapped people can live together, or normalization. In connection with this, Stuart [20] found that 78% of people with mental illness in Canada have felt stigma while at work. Moreover, in an interview survey targeted at patients with bipolar disorder, Michalak et al. [15] found that half of the respondents reported workplace stigma. The present study also found that people with mental illness experience being treated differently by other people in the workplace too (Table 1). Bender and Farvolden [21] described stigma experienced by patients with manic depression. Thus, many studies have reported that people with mental illness feel stigma in the workplace. Such situations are attributed to unsatisfactory working environments for people with mental illness [20] . Participants in the present study also felt anxious in anticipation of workplace stigma, creating a situation in which stigma prevents them from disclosing their illness. Anxiety that stigma after illness disclosure might lead to dismissal, delayed or withheld promotions, or demotions can result in psychological isolation at work owing to hiding the mental disorder, avoiding contact with other people, disliking social activities, and withdrawing from the workplace. Those who react to stigma by minimizing their interaction with society will furthermore inhibit their adjustment to society, slow their recovery, and tend to become isolated. These occurrences have a negative impact on their work, income, social status, and self-evaluation [22] . In this study, one request for employers mentioned was taking measures to cope with stigma. For people with mental illness to continue working, such measures must be taken to decrease workplace stigma.
6.3. Workplace Education about Mental Illness
The identification of education and consideration for the illness as requests by people with mental illness for their employers indicates that strengthening mental health education and public awareness is needed, especially in the workplace. In Japan, education about mental disorders targeted at employers in general is insufficient, and employers have not gained adequate knowledge or learned effective strategies for coping with these disorders. Without adequate mental health literacy, people are at a loss as to how to deal with people with mental illness; they cannot understand the necessary considerations. It is generally thought that stigma decreases when the diseases and the patients are understood [23] . A lack of knowledge can lead to stigma, so the spread and promotion of knowledge are urgently needed.
6.4. Illness Disclosure and Career Advice for People with Mental Illness
In Japan, various types of support are available for individuals with mental illness in the community, but this mainly involves medical care. Workplace support systems for these individuals, to say nothing of ways to support their illness disclosure, have not been established. Creating a support framework is necessary, because leaving illness disclosure to the person concerned without providing them with support will hinder prompt intervention and potentially lead to discontinued employment. Organization is needed to raise the employment rates of people with mental illness and to strengthen workplace support for them. This includes not only employers’ efforts at gaining knowledge about mental disorders and mastering how to manage people with mental illness, but also an improved organizational framework in which people with mental illness themselves can continue working and manage their illness at the same time. In other words, employers would be asked to create a workplace environment in which measures are taken to decrease discrimination so that employees can easily discuss their illness as well as work without having to disclose it. In this study, disclosure by other people was identified as a reason for disclosing mental illness. This implies that other people reported the illness in the workplace even when the person concerned did not intend to do so. Disclosure out of necessity and disclosure to continue working were also identified reasons, clearly indicating that people with mental illness are sometimes forced to disclose their illness against their will to continue working.
7. Conclusion
Taken together, all of the findings to date highlight the following needs: to understand the feelings of people with mental illness and make workplace support available for them, to use and coordinate social resources, to increase opportunities for private consultation and communication with people with mental illness, and to set up and maintain a system for carrying out and following up on all of these needs.
