The SEC is strongly reviewing if corporations are ensuring that informants are protected.

The SEC will not permit a retaliation.  The SEC is seeking to determine if corporations are retailing against individual persons who submit internal complaints.  As one indication, the SEC is reviewing personnel files to ensure that there is no negative reference to these individuals who have informed on corporate misconduct. 

In sum, corporations need to protect themselves from this type of review.  Reporting corporate misconduct is serious enough without then being accused of retaliation.  Avoid it like the plague!!
