Answer: Employers should offer employees enough opportunity to keep each of their drives in balance. 
Explanation:
The Four-Drive Theory is a way of improving Employee motivation through more ways than just financial incentives. It is believed that all four factors are very integral in the motivation of employees and so managers would do well to implement them to get the best out of their employees. 
The Four drives are, <em>Acquire and Achieve</em>, <em>Bond and Belong</em>, <em>Create and Challenge</em> and <em>Define and Defend</em>. 
A key recommendation by the proponents of this theory is that Managers should not give their employees too little or too much opportunity to follow each drive but rather give them enough opportunity that they keep each drive balanced with the others.
