It may have been a shock when an employee came to you with information about wrongdoing in your company. Perhaps it involved acts of discrimination by a trusted colleague or sexual harassment from one of your managers. Maybe the employee even pointed the finger at you. You have a lot to do to deal with this situation including an investigation, perhaps the involvement of law enforcement, and possibly the discipline and/or termination of the offender.
How you deal with the whistleblower is also something about which you should be concerned. Whether you feel offended at your employee's accusations or you genuinely want to protect your worker from further harm, it is critical that you proceed with caution to avoid appearing as if you are retaliating against him or her for blowing the whistle.
