There is a new OSHA Whistleblower Protection Program Web site. The site includes SOX complaint and outcome statistics at OSHA, as well as statistics for all of the other whistleblower statutes administered by OSHA. Here is a link to the statistics OSHA is tracking.
Current data on the site runs through 3/31/12 (Q2 of FY2012). So far this year there has been a slight uptick in SOX complaints compared to last year, but not by much, and not yet approaching complaint levels from prior years (2005-2010). According to the statistics, there have been zero merits findings for SOX complainants in OSHA investigations so far in FY2012, and there were only 2 such findings in FY 2011.
