NOT-- if::
(A) you were a "favorite" of the boss, or management, or,
(B) the management already "had it in" for the other person anyway, or,
(c) not if part of the management was in on the prank or harassment with you.
In such a case, the VICTIM is the one who is blamed and usually left with no choice but to leave.
Small companies get away with murder.
Not in my case.
BINGO.
I see this happen time and time again. The company finds that it is 10 times easier to let the "complainer" just go, and not deal with or address the harassment. It saves them time and money in the short run, but not the long run when high-turnover starts costing them serious money and productivity goes way down. Only then does the company finally deal with the situation.
