 Controversies and disputes have arisen from a diverse source of group such as People for the Ethical Treatment of Animals ( PETA ) over the welfare of animals , governmental and social agencies over health issues and compliance with nutritional labeling laws , and unions and trade groups over labor relations and laws . These situations have touched on the concepts of animal rights , corporate responsibility and ethics , as well as social justice . While the majority of the disputes did not result in lawsuits , in many of the cases the situations raised legal questions , dealt with statutory compliance , or resulted in legal remedies such as changes in contractual procedure or binding agreements between parties . The resolutions to these legal matters have often altered the way the company interacts and negotiates contracts with its suppliers and franchisees or how it does business with the public .
