Agree with Patrick on your next steps.  So go do that.<p>My breakdown of the reasons to terminate:<p>1. New employee did not follow broadly understood&#x2F;legal courtship protocol with female colleague.   [e.g.: On tinder&#x2F;okcupid&#x2F;etc., you can try your luck with &quot;DTF?&quot; or &quot;You&#x27;re a lovely MILF.&quot;   Doing the same with a work colleague (regardless of whether on the clock or not) is broadly accepted to be harassment.   Why?  Because the parties are both colleagues who have to work together.   On okcupid, a recipient of &quot;DTF?&quot; can immediately block the sender.  Not so easy to do a colleague.  Our legal system protects workers from harassment.   &quot;MILF&quot; isn&#x27;t just a query about going out for coffee.   It is a GOTO jump over many protocol stages without ACKs from recipient.<p>2. New employee is either ignorant of work-based courtship protocol, new employee actively chose to disregard it, or perhaps new employee was drunk during the exchange.   It doesn&#x27;t really matter.   Either way, the guy does not meet the standards to work in a professionally run company.<p>3. By so flagrantly violating a commonly understood protocol [workplace courtship] very early in his employment, the guy is demonstrating to his boss that he is not worthy of trust and responsibility.   Terminate him.<p>As for those few of you who think the guy should be given a break, this is corporate worker bee 101 stuff.  Sure he is sexually interested in a colleague.   There is no problem with that.  The thing that is for very good reasons, your fellow workers are protected from harassment.   Dating a fellow worker requires running a very different courtship protocol than picking up someone in a bar or over tinder.<p>Unless you feel qualified to run corporate-dating-protocol from start to finish (what will you do post hook-up&#x2F;break-up?), please consider the advice of our forebears: don&#x27;t dip your pen in the company ink.
