JKen:A person who works for Company A has caused emotional distress to . . . my wife by having an affair with her.
You understand how ridiculous this sounds, right?
JKen:how can I make this guy understand how painful it is for families to break apart.
This is not a legal issue.
JKen:How do I report about him at his company?
It's not even remotely clear what your wife's adulterous conduct with this man has to do with his employment. Nevertheless, you can tattle on him by picking up the phone, writing a letter or an e-mail, or visiting his place of employment.
JKen:Where is accountability in this country and society. There are laws to punish every criminal act but is what he has done any less crime?
Adultery is still on the books as a crime in a handful of states. California is not one of them.
JKen:Isn't the society accountable for the kind of people they have around them?
Huh?
JKen:Aren't companies and colleges accountable for the kind of people they employ?
In some contexts yes. For example, if a pizza restaurant employs Bob as a delivery driver and Bob negligently causes an accident while in the process of delivering a pizza, then his employer will be vicariously liable for the damages caused. On the other hand if, on Bob's day off, Bob attends a local chili cook off, becomes intoxicated, and physically attacks someone who suffers significant medical bills as a result, his employer will have no liability. To put it more broadly, employers are not generally liable for any bad act that any employee commits, regardless of whether it has any connection whatsoever to the employment relationship.
JKen:Isn't the person accountable for his actions? For ruining a family?
There are a couple states (and I literally mean only a couple) that still recognize a civil lawsuit against a person who commits adultery with a married person. California has never recognized such a claim.
JKen:Isn't talking sexually, luring for sex by playing with emotions a form for sexual harassment?
The term "sexual harassment" has no legal meaning outside of the employment context. If a supervisor is constantly subjecting a subordinate to sexual advances and sexual talk against the subordinate's wishes, then the subordinate may have a sexual harassment claim against the supervisor and possibly also against the employer. Did this man and your wife work together and, if so, what she his subordinate?
JKen:Isn't doing this during company time and at company's expense make it a liability for the company he works for now?
No because, unless his employer is some sort of male escort service, engaging in conduct relating to an adulterous relationship with your wife was not within the course and scope of his employment.
JKen:Didn't the employer fail to exercise reasonable care on the employee.
I have no idea. However, even if it did, it's not legally relevant.
JKen:What if he made the first move and then threaten with reprisal when rebuffing repeated advances? Not sure if that can be proved though. Can we still complain?
If the guy and your wife worked together and she was a subordinate (I'm not sure if we're supposed to assume that is the case, but your post is silent about this), then you are describing a classic case of sexual harassment. Obviously, you can complain to whomever you like, but one of the main issues will be whether your wife has suffered any adverse employment action as a result of this man's conduct. Your post is silent about this.
JKen:Shouldn't corrective/preventive actions be taken against such individuals by the employers?
In a perfect world, yes. This is why larger companies have sexual harassment training. However your post is completely silent about whether their employer (assuming they worked together) knew about what was happening. Did your wife report what was happening to her employer (e.g., someone in HR or this guy's supervisor).
JKen:Can we report about his actions to his employer and request for disciplinary action?
I can't believe you think there is any reasonable possibility that the answer to this question is anything but yes. You obviously can report anything you like to anyone.
JKen:What if this person ruins another family tomorrow?
"What if?" questions are often some of the most useless questions ever.
JKen:Who will make him realize the mistake? Who will stop him? When will he stop?
If it happens again, maybe the next guy's husband will be a gun enthusiast with little regard for homicide laws.
JKen:Shouldn't his family know kind of person they have in them?
Not a legal issue.
JKen:Isn't he responsible for the emotional distress he caused to our family?
If this guy was a co-worker of your wife, if she was a subordinate, and if, as a result of this conduct, she suffered adverse employment action or she reported the action and the employer failed to take reasonable action to stop it, she may be entitled to recover emotional distress damages against him and/or the employer. If these conditions are all true, she should consult with a local employment law attorney.
JKen:How do I get protection from being retaliated for complaining?
Can I report in advance to the police anticipating retaliation?
As I said previously, you can report anything you like to anyone. However, you should step back and think about this for a second. Imagine you are a cop and a guy walks into the police station where you are manning a desk. He says, "Hello. I would like to report that my wife is having [or had] an affair with a particular man. I reported the affair to the man's employer and I want to report that I 'anticipat[e] retaliation.'" How would you react to such a report? What exactly would you have the police do in such a situation based on nothing more than an unsupported allegation (even if true) and a bald suspicion?
