You're in a bit of a quandry. He should be go, but it's not going to be easy. If you fire him for this instance, you could be sued for wrongful termination, and in which case you would have to produce those whatsapp messages, and convince your employee that they were harmful. > He asked to take the conversation off Slack (moved to Whatsapp) and asked if they could hang out (she said, "sure as friends in work context"), referred to her as a milf (ugh...), and asked if he could tell her a secret (she refused) My interpretation was this person used Slack (work resource) to ask a coworker to switch to Whatsapp (non-work resource), during the weekend (non-company time). He proceeded to make inappropriate comments on whatsapp. I'm not a lawyer, but from limited research, it seems that a few sets of inappropriate text messages (of which you dont approve of, but the recipient doesn't mind) sent over the weekend does not constitute workplace sexual harassment. The employee has said "it's not a big deal." which even though you don't like it, means it's somewhat out of your hands. The quandry is, the bizdev person is probably a bad fit for your company. You should get rid of him, but would need something more substantial in order to standup to a wrongful termination suit.
