@stanleybmanly I don’t know if that is a criminal offence. If he molested her and you were witness, then that’s a crime, but, like was mentioned by so many in another post, in the US, folks can just be fired. She’d never be able to prove that she was fired for not giving him a sexual favour. He said, she said situation and you’d be third party hearsay.
But if you know someone is embezzling money and you don’t tell, you are an accessory. Any sort of theft. Any sort of threats of blackmail, kidnapping, violence. Especially if you are some how benefiting by not saying anything and they can prove that you knew about it… like if a mate stole the test answers and shared them with you, or beat up and scared off someone you wanted gone that you would benefit from, like create a vacancy in an apartment building you wanted or such like. It is a crime. I’ve known of a woman who was caught embezzling money from her employer and she had bragged about it in correspondence on her work computer to her family members…. for a very long time. Her mother and brother found themselves in court as well.
