Gena is the hiring manager for Wired Lines, an electrical wiring service. When she looks at the current state of the company, she sees that the employees and management do not have much mutual trust or respect, guidelines for performing jobs are very inconsistent and ambiguous, and the supervisors have little authority to make changes or take action. She feels that the situation is a mess, but she needs to hire a manager to oversee several teams of electricians. Which person should she hire to most effectively lead in this situation?
