I don't suppose he meant any harm but it does seem odd.
The phone stuff didn't happen in years past but has done now for a long time.
About two years ago I had dealings with a young woman, attractive, early 30s, who had a couple of pictures sent to her by email from a man in his sixties,near retirement age, whoworked in her building.
It was very stressful for her, she's a quiet rather shy girl. He kept on harrassing her (in jokey way), the photographs of his privates was the last straw. I saw them.Thinking about it again now, how dared he. I told her the first thing was to go to HR and show them the emails and pictures which she did, took someone with her, and would you believe they laughed it off.
She could have taken it further but just wanted it to be over,was easier for her to get another job. She was off sick for a while with anxiety before she did that but that's what happened in the end - while he stays to insult someone else unless he's retired since.
