In any employment case, there are things to be learned or reaffirmed:
Tip for the Lawyer: Always find out what the earliest point in time was that the client first opposed the harassment. Look for adverse actions that were taken starting at that point, because usually they commence then, no matter how subtle they might seem.
Tip for the Client: Sit down and prepare a journal or notes addressed to the lawyer (and kept in a safe place at home) outlining any and all events that happened after she first told the guy to stop pestering her. Have her prepare it in a chronological manner and then discuss each event with her in greater detail and identify any witnesses or documents which might support their occurrence.
