The OFCCP uses a questionnaire to determine when a subsidiary company's government contracts implicate the parent or a subsidiary company's government contracts implicate other sister subsidiaries. https://webapps.dol.gov/elaws/ofccp/fcca/assessment.asp This typically requires the employer to gather the facts in response to the questions and then seek a legal opinion about whether the facts support a single entity conclusion. If there is any way for you to take this question out of the public forum and ask it privately, I would encourage you to do so.
