Do not tell anyone you are looking for a job...

A relative of mine was looking for a job and she was invited for a job interview. She told two ladies at her current job that she was going and which company it was. At the interview the manager said:
- We have had an anonymous phone call regarding you. This person also told us a lot of negative things about you and that we should not hire you.
So folks, do not tell anyone at your current job that you are looking for a job....it could backfire as there are some really evil people put there. As far as I know she did not get the job either.
