Recognition
You must recognize that people have differences, be they physical, generational or cultural, and you cannot pretend that these barriers have been broken down. Instead, celebrate the differences among your employees, and encourage them to let their individualities show. For example, don't hesitate to ask someone from another culture about their culture's etiquette practices -- their knowledge could prove useful to your business. Do not pigeonhole your employees. An employee's worth comes from more than his ethnicity or age.
