"If you find out one of your colleagues identifies as LGBTQ+ on dating apps, but isn't out with their identification at work, the first thing is to accept that there's probably a good reason for it," said Toby Hervey, cofounder and CEO of the career-coaching app Bravely, told Business Insider.
"They might be early in their journey of coming out or just a private person in general — don't jump on the gossip train and start spreading what you discovered."
Hervey also said that if the person hasn't come out to coworkers, it might not just be a personal thing — "maybe your workplace culture is part of it," he said.
If you manage the coworker directly, you can reflect on your own management style and whether you're fostering their comfort in sharing more. If it's your superior, although it may be even more tempting to share your discovery, respect your boss' privacy and remember they are "human and vulnerable too," Hervey said.
Regardless of who the coworker is, you can use the moment to help your workplace become more inclusive and a better place for everyone, no matter what level you are or what your relationship is like with them.
