While full disclosure of your sexuality can help you earn fair treatment from your colleagues, kindly note that it can also earn you a termination. If your company has zero tolerance for homosexuals individuals and they did not know this before hiring you, best believe they might have to terminate your employment with them. However, if your company has nothing against homosexuality but its workers just seem to have little to zero regards for homosexuals, you may of course walk up to your employer to let him/her know about your orientation and how you’re not comfortable with how your colleagues speak about homosexuals. A better environment might be created. And that’s great!
