Najjar's activism focused on rural development and women's lives. She worked for the establishment of schools and clinics accessible to rural families. In 1953 she and
Evelyne Bustros founded the Village Welfare Society, to advance literacy and economic opportunities for
rural women in Lebanon. She created a certificate, the "Rural Brevet", as an incentive for women to attend her the society's practical workshops on literacy, childcare, nutrition, hygiene, and agriculture; the program soon expanded to include some content on broader topics such as literature, politics, music, and religion. She served as secretary of the Lebanese Council of Women, and as general secretary of the Druze Orphanage from 1948; she also helped found Lebanon's League for Good Housekeeping. Outside of Lebanon, for five years during World War II, she was principal of two girls' schools in Iraq. A Lebanese postage stamp featuring Najjar's face and name was issued in 2014, soon after her
100th birthday. She was also awarded the Lebanese
Order of Merit medal, twice, and the Lebanese Army Shield. ==Personal life==
