Do you expect loyalty from your employees?

Let's refine this question. To what extent do you expect loyalty from your employees? At one extreme, some traditional companies may think it normal for an employee to work for them for life. They also expect to provide for the employee and his family for life - job security, benefits, perks, insurance and so on. Loyalty goes both ways. At the other extreme, some companies are mercenary in nature, treating all employees like contractors, hiring and firing purely based on business (i.e. profitability) needs. No loyalty is expected. It's just business. If you employ full-time employees, how much loyalty do you expect from your people? Or in what forms do you expect loyalty from them?
