You will find that people do talk about their personal lives while at work. No, I'm dating, but not in a committed relationship. As you move through your coming out process, you can talk casually about how you spent the weekend. Some will be overly supportive, a few may be antagonistic, and the majority will simply accept you for the value of your work, not your personal life. Sometimes, no matter how much research you have conducted, you may find yourself in a difficult situation.
Discrimination can be subtle or obvious, individual or institutional.
In any case, it is important to identify the problem and take appropriate steps to deal with the situation. If you feel that you are the target of discrimination based on your sexual orientation, the first step you must take is to conduct an honest evaluation of the circumstances. It's always difficult to hear that you need to improve your work, but it doesn't always mean that you are being discriminated against due to your sexual orientation. It's always a good idea to take some time after a negative review to let emotions cool off so that you can assess the situation more clearly. The key to identifying discrimination is having documentation of specific incidents.
