Federal contracts require you to bend over backwards for disabled people (now that I phrase it like that, it does sound bad, but replace disabled with Israelis and it's the same thing): https://www.dol.gov/agencies/ofccp/faqs/section-503
They go against the market to bend over backwards for certain other groups of people: https://www.sba.gov/business-guide/grow-your-business/become...
This is not really bending over backwards, but they do need you to spend additional resources on other shit as well: https://www.employer.gov/EmploymentIssues/Federal-contractor...
Don't be surprised to find out that the federal government doesn't believe in the free market.
