Meno: the issue was more about talking to coworkers. My friend trusted her coworker and considered her a friend. She did not think she would repeat word by word exactly everything she said to their boss, including other priavte thoughts and details that were unrelated to her paycheck.
She trusted her coworker, the message is that when it comes to parnassah people can do crazy things, take caution even around those who you consider your friends.
