They are more than allegations if he’s been sacked - BBC wouldn’t dare do that without incontrovertible evidence and following due process.This may not apply to Jenas, there are only allegations so far and nobody reputable (even the tabloids) has enough to publish the story yet.
But as a general rule of thumb, never send inappropriate texts, even compliments on appearance, to colleagues or acquaintances you aren’t already in a relationship with. Don’t do this when you’re married. Especially don’t do this when you’re a high profile public figure.
And NEVER send intimate pictures to anyone without their absolute consent (in writing, so you have evidence). Think “if this were exposed (forgive the pun), would I be able to defend it in a hypothetical court with evidence”.
This kind of stuff makes up the vast, vast majority of HR cases.
**an aside**
A large number of cases of “unwanted sexual conduct”, such as unsolicited dick pics or sexual messages, come from two things IMHO.
1. Substances. Don’t get drunk and try it on with your fit colleague.
2. Misread signals. Don’t think just because a colleague is friendly at work that they secretly want you. So many men don’t realise that just because a woman is nice to you, that they want to have sex with you.
I know a guy like this, who thinks every woman who so much as smiles at him is interested. He’s been banned from a few places for macking on waitresses. Absolute sleaze. I can guarantee if he got their numbers, it’d be unsolicited dickpicpalooza.
