TNCs like Nokia locate branches globally to minimize costs and be close to customers. Nokia opens factories and offices where labor and real estate are cheap. It also expands into growing markets as consumers in developing countries become wealthier. Nokia employs different types of workers in different locations based on skill level. Highly trained R&D staff work in Europe developing new technology products while basic assembly occurs in lower cost countries. Factories can impact local environments but also provide jobs and skills training for local communities.
