Business culture in America

Americans take business very seriously. Professionalism and punctuality are expected. When doing business in America, expect a heavy reliance on facts and numbers. A scientific approach is the norm for all aspects of business, even the human relations department.
When meeting business partners for the first time, American’s culture expect a handshake, not a hug. Address your business partner as "Mr." or "Ms." followed by the person's last name. He will generally invite you to call him by his first name. After the initial contact, communication similarities end. Americans prefer blunt speech. Tactfulness is seen as wasting time.
Americans pride themselves on their egalitarian culture, and everyone is encouraged to speak up and disagree with a higher-ups. Passionate confrontation may take the more reserved Canadians aback. These confrontations, however, almost never stem from personal animosity, but rather from the business culture of the country.
In America, management still is very individualistic. Managers are held personally accountable for decisions. They assume any consensus will dissolve as soon as an initiative hits rocky ground, so American managers are less willing to compromise and play politics. However, this approach can lead to resentment and confrontation if subordinates believe their voices are not being heard.
Formal business dress: dark business suits and ties for men, and pants or skirts with a suit jacket for women. Beyond that, however, dress code varies widely with the location, industry, and corporate culture of each institution. In America, more progressive industries, such as technology, tend to have more relaxed dress codes.
