In the company of givers and takers.

Employees make decisions every day about whether to contribute to others--and their willingness to help is crucial to group and organizational effectiveness. But in a competitive, often zero-sum, world of work, generosity can be a dangerous path. How can leaders foster it without cutting into productivity, undermining fairness, and allowing employees to become doormats? The key, explains Wharton's Adam Grant, is to help givers reach a more nuanced understanding of what generosity is and is not. They'll be better positioned for sustainable giving when they can distinguish generosity from three attributes that often travel with it: timidity, availability, and empathy. Givers can overcome timidity, Grant says, by learning to act as agents--using "relational accounts" to advocate for others while negotiating for themselves. They can set boundaries on when, how, and whom to help. And they can strive to be perspective takers, not just empathizers, gathering knowledge about others that can lead to more-productive allocations of time that will benefit the organization as a whole.
