An Employer's Oral Warnings May Not Prove They Tried to Prevent Harassment and Misconduct!
In other words, don’t let promises from your employer, regarding someone being written up or “spoken to” about misconduct guide your decisions as to whether or not your employer is providing ample protections for you under the law. If you have been the victim of substantial and pervasive misconduct, the punishment of the offending individual should be more significant. For instance, it may be more appropriate that the individual be demoted, transferred, etc. Only you know the severity of your situation, but you should demand whatever punishment fits the crimes committed against you.
Additionally, your employer’s response to misconduct should be immediate. If your employer does not immediately correct pervasive misconduct, they are opening themselves up to legal jeopardy.
