John, HIM department director, recently redesigned the orientation program for two new employees who were assigned to work remotely as coders. After two months, both employees resigned their positions. John is wondering what he can do to prevent this from happening again. Which of the following would you suggest to John?

Spend less time with the employees on their first day and let them work independently

Complete the program in no more than $4$ hours

Emphasize that the employee handbook serves as a contract

Review the evaluation forms completed by the employees immediately following the orientation program for ways to improve the program.
