As the human resources manager, marcus knows it is important for the company to develop a program for expatriates who return to work at the home office. what type of program is marcus referring to

Marcus is referring to mentoring program .

Explanation:

A person residing in a foreign country other than his or her country is an expatriate. In general use the term refers often to skilled, qualified workers or musicians, whether individually or overseas or sent outside their country by their own employers, who can be businesses, schools, governments or NGOs.

A mentor with cultural experience will deal with and ease the challenges that are so often encountered internationally by international workers from a "real" viewpoint.  

Create a mentoring program so that returning expatriates can provide existing and future ex-pat workers with information and support.
