To successfully motivate co-workers (which is the term I used for anyone who worked at my companies)—to get them to take actions that you want and need them to take in order to improve customer service, increase productivity, and attract new customers—you must reward them.

1) recognition
2) self-esteem boosts
3) spiffs (commissions)
4) career growth
5) working for a great company
