McDonald's used several strategies to change consumer attitudes: 1. It addressed myths about its food quality and production processes through educational video campaigns and fact-checking websites. 2. To improve perceptions around workers' rights, McDonald's implemented employee recognition programs and incentives to reward and retain key staff. 3. By adapting menus to local tastes in countries like India, Germany, and others, emphasizing vegetarian options, McDonald's was able to better cater to cultural and dietary preferences in different markets.
