"The agreeable giver may seem like the ideal employee, but their sunny disposition can make them averse to conflict and too eager to agree. Disagreeable givers, on the other hand, can be a pain in the ass, but valuable to an organization.

They’re more likely to fight for what they believe in, challenge the status quo, and push the organization to make painful but necessary changes. And because they’re stingy with praise, when it’s offered, it generally can be trusted.

Disagreeable givers “can get more joy out of an argument than a friendly conversation” and be tough to work with. But for organizations eager to avoid complacency and determined to improve, they also can be invaluable."
