The literature exploring the impact of lesbian, gay, and bisexual (LGB) supportive employment policies on work and life satisfaction and how these relationships reflected business outcomes is largely derived from the LGB workforce in Western countries. To our knowledge, empirical evidence from LGB workforce in Thailand is very limited. To address this shortcoming, this study aims to identify and evaluate the work-related supportive factors that influence job and life satisfaction of Thai LGB employees. Theoretically, the study offers novel aspects of LGB employees’ perception toward their workplace environment in different social and cultural context of Thailand. Online surveys were administered to 144 LGB individuals, and the results highlight the effects of three types of support at work – supervisor, organizational, and coworker – on Thai LGB employees’ job and life satisfaction. The findings also provide insights for human resources managers to attract and retain LGB employees.
