Characteristics of department networks^a

Department	Reciprocity (%)	Missingness (%)
Green	55	12
Yellow	54	44
Red	48	30
Blue	43	18

^aReciprocity within data from survey respondents was sufficiently high to assume reciprocity among all departmental colleagues. Missingness is calculated after assuming reciprocity and indicates the percent of ties in a network for which we have no data.
