LGBT+ persons in science, technology, engineering, and mathematics have a small growing body of literature addressing their experiences and workplace concerns. This study offers workplace climate analysis of 324 survey respondents in the field of physics. The findings indicate that when building a climate model to predict for consideration to leave and outness, a positive workplace climate was a stronger predictor than a negative workplace climate or experiences of exclusionary behavior. This points to the importance of moving beyond workplace climates that are simply neutral, but to ones that are inclusive and welcoming for LGBT+ physicists. This is the final paper in a series of three. [For "LGBT+ Physicists: Harassment, Persistence, and Uneven Support," see EJ1343502.]
