One common reason behind restructuring a company is usually to downsize the workforce. The changing nature of economy may force the business enterprise to adopt new strategies or alter their product mix, making staff redundant. Similarly, cutthroat competition and pressure on margins from competitors who adopt a low price strategy may force the company to look at lean techniques, just over time inventory, and other measures to reduce input costs and achieve process efficiency. The McLibel case ranks as McDonald's most disastrous cases of bad business ethics and spawned a great deal of negative publicity. Between 1986 and 1990, activists of London Greenpeace distributed pamphlets while using title 'What's Wrong with McDonald's? Everything They Don't Want You to Know" along with the wordings 'McDollars, McGreedy, McCancer, McMurder, McProfits, McGarbage," alleging that McDonald's promoted Third World poverty, sold unhealthy food, exploited workers and children, tortured animals, and destroyed the Amazon rainforest. McDonald's sued the group for libel. The court, however, held McDonald's responsible for exploiting children through advertising tactics, serving dangerously unhealthy food, paying workers low wages, enjoying union busting activities worldwide, and ignoring animal cruelty perpetrated by its suppliers.
