A car rental company is experiencing high turnover among assistant managers and many new assistant managers are not meeting performance expectations. This is causing the company to lose credibility among its customers. The current selection process for assistant managers involves a phone screen with a thirdparty company. During the phone screen, applicants are asked to talk about their work experience and to describe why they are interested in the position and working for the car rental company. All candidates who meet the minimum qualifications for the position and demonstrate enthusiasm for the role and the company are recommended by the third-party company to the branch manager for an in-person interview. Branch managers interview these candidates and have the freedom to develop and ask their own interview questions. Ultimately, the hiring decision is left to the particular manager 's judgment. Senior leadership asks the HR manager to review the selection procedures and provide recommendations for improving talent management.
The HR manager learns that customers' car reservations are incomplete because assistant managers are quitting and no one is taking the initiative to complete the work they had not finished.
Which action should the HR manager recommend to branch managers to resolve this?
