Which influence technique occurs when leaders establish their authority as a basis for a resource requisition when it may not be obvious?

The influence technique you're referring to is known as "legitimating." In this approach, leaders assert their authority to justify resource requests, even when the necessity for those resources isn't immediately apparent. By invoking their position or expertise, they aim to gain compliance from others, leveraging their status to legitimize the request. This can create a sense of obligation or respect that encourages others to support their initiatives.
