B　　Running your small business requires good staff. Once you find them, you don't want to let them go elsewhere.　　During an employee's time with a company, there are a number of forces that influence his or her behavior. I like to refer to them as "push" and "pull" . You're either pushing an employee towards the door, or pulling them deeper into your organization.　　Suppose that you've made a good hire and you want to keep the employees, the trick is to recognize individual needs of employees and satisfy those needs, within reason, in order to keep pulling them away from the door. Even if you can't pull them away from the door, at least don't do things to push them out of the door.　　Recognize that some employees will lose interest and need something fresh to keep their interest. If you can't continually provide challenges, opportunities for promotion and other interesting and rewarding opportunities, then you'll have some employees leave through no fault of your own.　　The important thing is to identify your key employees and make certain they are being treated well. Communicate with them on a regular basis to make certain that you understand what makes them behave in a particular way, and be aware of concerns they may have about job satisfaction.To keep your employees, you are advised to _____.A. recognize and meet their needsB. identify and overcome their faultsC. offer them a salary as high as possibleD. provide them with a better working conditionAccording to the passage, when is it possible for some employees to lose interest?A.
