The best way for sales managers to instill ethical behavior in the sales force is to

A) provide extensive ethical training.
B) use only straight salary and no commissions.
C) use other salespeople as ethical models.
D) never use telemarketing.
E) lead by example.

Leading by example is the most effective way for sales managers to instill ethical behavior in the sales force. If the sales manager models ethical behavior, it sets the tone for the entire team to follow. Extensive ethical training and using other salespeople as ethical models can also be effective strategies, but they are not as powerful as a leader who demonstrates ethical behavior in their own actions. Using straight salary and no commissions may reduce unethical behavior related to sales incentives, but it does not address other forms of unethical behavior. Avoiding telemarketing is a specific tactic that may not be relevant to all sales teams.
