Thanks Jup for more complete picture. And, I play devil's advocate usually ... because I hate the press in how they try to spin things (like only reporting at end how Indians were not notified about any of this other than the husband). I try to look at things from all sides.
In all of this, the only real easy offense to fire him with is the reporters who had unwanted sexual advances (crutch stuck in their face or asking for nudes). This is where he is on company time, doing company work and needs to be completely above board. Unfortunately, this is the hardest thing for the Indians to investigate without a complaint because if they are wrong on how far he was taking things, you are feeding meat to the wolves and giving reporters a story that may not be true. If they knew about this (or the Mets found out about an incident in Cleveland) and did not do a full investigation, that is a problem. But, so far, it is just his open secret in Cleveland about his behavior which at the time was being unfaithful.
And, even him sending a woman he is dating a full nude in the locker room is bad but not really a termination offense because it is his private life. It is one thing to do it in an office as someone said because another employee can walk in. But, to snap a pic of yourself as you are changing in a "male" locker room during non-press time (and not getting anyone else) is that a crime? Now, if he shared this to a broader audience on internet, that is corrupting the Indians image. Yet, it was only to a woman who saw him fully already, just checking in to see how things are going that day as many husbands do with their wives at work (without the pic of course). The employee seeing it is why you don't do it but it was her friend who showed it to her not Calloway himself (probably because they were talking about it and the employee asked to see it). But, if a complaint was filed here, Indians should have looked at it (sending porn to those who don't want it that you are not romantically involved with).
As for the "pass" and "suggestive message" to another employee, that is the big grey area of our times and causes HR department headaches. But, note how this was short and sweet and not that descriptive. There is nothing wrong for a non-manager asking someone out from a different department. It is creepy as hell if he is married and 20 years older probably. Yet, I asked out another employee who worked in a different department when I was a low-level manager. You may call it a pass, so should I have been fired? The suggestive language is troubling but how suggestive is it if not really quoted would be my question to see how far he crossed the line.
I don't condone any of this. But, as a manager, I would have talked with him (Tito fined him) but could you fire someone for what is listed other than the reporters? That was the bind Tito was in .. and he couldn't look into the reporter angle (to ask about his relationships and behavior towards them) without killing his team in August with a major distraction for something he did not know about.
