The manager repeatedly brought the issue up to him. How come the employer rules don’t apply to her?
Well, women talk - about everything and frequently, in my experience. What if she had been talking about her son's Bar Mitzvah, or Kwanzaa, or her Passover Seder?
If he thought the conversations were inappropriate for the workplace, then he should have said so, and left it at that. But, he shouldn't have offered his moral judgment on her personal life, just like he shouldn't say that a Bar Mitzvah is immoral or Kwanzaa is racist.
