OSHA answered this question in a press release issued this week:  They will come after the offender until they collect, plus penalties!

Just ask Vasilios Saitis, owner of Altor, Inc. a construction company in New Jersey who was found in contempt of court, and was not only forced to pay the original $412,000 OSHA fine for multiple safety violations, but also $30,000 in penalties, not to mention all of the legal fees that accrued during extensive litigation.

This statement summarizes the case:

“This successful outcome demonstrates that the U.S. Department of Labor will use all appropriate and available legal tools to ensure that employers do not evade accountability for failing to comply with the Occupational Safety and Health Act,” said Regional Solicitor of Labor Jeffrey S. Rogoff, in New York. “Our collaborative efforts in this case with Assistant U.S. Attorney Jordan Anger, from the U.S. Attorney’s Office District of New Jersey, help ensure that workplaces are safe and that employers who violate the law do not gain an unfair economic advantage over law-abiding competitors.”
