Final answer:
Competitors of Burgers R Us are the least likely to discuss changes in purchasing meat with the company when facing reports of unsanitary practices, as they are not directly involved in the internal decisions of the company's supply chain.
Step-by-step explanation:
In the case of Burgers R Us in Saskatchewan, facing news reports of sub-par hygienic practices by their beef supplier, various stakeholders would likely discuss a change of approach to purchasing meat with the company. These stakeholders include customers, who would be concerned about the safety and quality of the food they consume; shareholders, who have a financial interest in the company's success and reputation; and government agencies, which are responsible for enforcing food safety regulations. However, competitors are unlikely to discuss purchasing strategies with Burgers R Us, as they are not a party to the company's supply chain decisions and have their own interests to protect.
