Introduction <p>Although limited research has explored the relationship between discrimination against lesbian, gay, bisexual, and transgender (LGBT) individuals in Japanese workplaces and their willingness to continue working, even fewer studies have identified the specific forms of discrimination that directly undermine this willingness. Furthermore, it remains unclear how LGBT-supportive policies and disclosing one’s sexual orientation at the workplace influence LGB individuals’ willingness to continue working in Japan. This study examined the relationship between discrimination, specific discrimination types, and LGB employees’ willingness to continue working. It also explores whether LGBT-supportive policies and disclosure of sexual orientation affect employees’ willingness to continue working.</p> Methods <p>An online survey was conducted with 2262 participants&#xa0;(number of valid answers) from the Niji VOICE 2018 between June 1 and July 16, 2018. Participants provided information about their age, sexual orientation, and other demographic and background variables. Partial proportional odds regression was used to analyze the data.</p> Results <p>Discrimination and specific discrimination were negatively related to LGB employees’ willingness to continue working. Conversely, LGBT-supportive policies and disclosure at the workplace had a positive relationship with willingness to continue working.</p> Conclusions <p>LGB employees who face discrimination and specific discrimination, including gender stereotyping and the spread of rumors about their sexual orientation, exhibit reduced willingness to continue working.</p> <p><b>Policy Implications</b></p> <p>Promoting LGBT-supportive practices in the workplace can enhance LGB employees’ overall willingness to continue working at their current jobs.</p>
