Would it be appropriate for me to tell people at work my sexual orientation?

You must do what is comfortable for you. If you feel like letting your coworkers know, go right ahead. But defiantly do not feel obligated to tell anybody you don't want to, it is totally your business and you can as you wish with it !

Of course it'd be appropriate, if you feel you are close enough to your co-workers and you want them to know the true you then go ahead.

Yes it is as long as you feel it's the right time and you feel that it's safe. It is completely appropriate though.

Yes, absolutely! It's important for workplaces to be accepting of all types of sexual orientations and gender identities and to embrace diversity. If anyone at your workplace comments negatively on your sexual orientation or treats you meanly because of that, that is legally classified as sexual harassment.

You can tell whoever you want about your sexual orientation. It's just as much of a part of you as your eye color or height or shoe size or whatever. The only piece of advice I have for you is that you may want to wait until you're relatively friendly with this person as oftentimes sudden revelations can startle people and make them a bit uncomfortable. They may feel as if they now have to confide something in you and that could make everything a bit awkward. But it's your orientation to tell, and do it whenever you feel ready!

l believe it is appropriate to tell as problems might arise if you don't tell anyone. At any work position, it is always best to be completely honest with all your actions and everything you say and such a thing like hiding your sexual orientation can affect staff/employees around you. So in my case as l will repeat myself, l feel it is best to tell people at work of your sexual orientation.

If they ask you or comment on it, then you should be fine to tell them. If you really want to tell them without them asking, casually drop it into conversation. I wouldn't advise announcing it over the PA system or throwing a parade, but there's no harm in letting your coworkers get to know you a little more. As long as you're not broadcasting your sexual exploits or coming on to your peers, there's nothing inappropriate about it.

You don't have to, if you don't want. Your sexual orientation is nothing to be ashamed of, and you don't have to state what you like to every single person you meet and worry about what they would think of you.

I don't see why it wouldn't be appropriate. Unless you work in a homophobic environment or you don't feel like you work in a safe space.

Your sexuality is a part of you, and if you feel comfortable sharing that, then do so! If it were to come up, it certainly would not be inappropriate to mention it. But, keep it professional as always.
