Amici include technology, materials, financial services, pharmaceutical, apparel, and entertainment companies; hoteliers and restaurateurs, service providers, consultants, and designers. Amici all share a desire to attract and retain a talented workforce. We are located or operate in states across the country, some of which recognize marriages of those of our employees whose spouses are of the same sex, and others that prohibit marriages between same-sex couples and refuse to recognize existing same-sex marriages. This dual and continuously shifting regime uniquely burdens amici. This legal uncertainty exposes us, as employers, to unnecessary cost, risk, and administrative complexity. In addition, this irresolution hampers our efforts to recruit and retain the most talented workforce possible, placing us at a competitive disadvantage. Our success depends upon the welfare and morale of all employees, without distinction. The burden imposed by inconsistent state laws of having to administer complicated schemes to account for differential treatment of similarly situated employees creates unnecessary confusion, tension, and ultimately, diminished employee morale.
