Final answer:
The baby boomers, born between 1946 and 1964, are characterized by their significant impact on culture and society, particularly their value for face-to-face communication in the workplace.
Step-by-step explanation:
The defining characteristic of the members of the baby boomers generation is that they were born between 1946 and 1964. This generation is known for coming of age during the 1960s and early 1970s, a period marked by significant social change and the development of a unique youth culture with distinct spending and marketing power. Baby boomers as they have aged, redefined what it means to be young, middle-aged, and now old. The assertion that they view face time as an important contribution to a successful work environment could be identified as a defining characteristic, representing their value for direct communication and interpersonal interactions in professional settings.
