In Michigan, my employer has asked for all employees to provide:
  • A copy of my birth certificate,
  • A copy of my spouse's birth certificate, and
  • Our marriage license.
They say they need these documents to "update their records". I'm not sure what that means... whether they're trying to make sure all their employees are legally entitled to work, if they want to verify marriages for health plan eligibility, something different, or more than one reason....

But are they entitled to this documentation? Can I propose an alternative (e.g., showing them my passport instead of a birth certificate) without getting into trouble?
