I'm the assistant manager of a small co. who received a harassing hate
letter from an employee.  It was disturbing and revealed a certain
amount of obsessive thinking, so I'm afraid.  What are the
requirements, if any, of my employer to investigate and help to ensure
this doesn't continue, and what rights to I have as an employee in
trying to find out who did this?  Oh, and I'm in Texas if that makes a difference.

Hi, Kaye5,

Sorry to hear about your hate mail.

It must be very disturbing.

But unless you can be sure who the writer is, there's not much that anyone can do.

One of my colleagues was the recipient of many such letters some years
ago and it took a long time to track down the writer as his personal
assistant, the least likely person imaginable, until she said
something that pointed unmistakably to her.

In the meantime, try not to worry because that would only add to the
writer's malicious pleasure.

All the Best

Bryan

Do keep the letter, it may become useful.
