I'm going to tell a future doctor to be careful about how revealing her pictures on social media are
Does she post inappropriate things online?
Yeah, I've heard a lot of complaints from one of the nurses about how she shows too much of herself on facebook
I see what you mean. Go ahead and tell her how her inappropriate social media posts may hurt her in the future. If you don't tell her now, she may certainly regret it in the future.
Yeah I'm going to tell her that online postings are always permanent
That's very kind of you to alert her about how her behavior is being perceived. Other people talking about her online posts without telling her how she's being seen is hurting her reputation. If you are tactful, I'm sure she'll be grateful!
