To examine the associations between organizational (bonding, bridging, and linking) social capital, employees' health, and employees' performance.
Linear regression on cross-sectional data among 718 employees in two Dutch companies.
Organizational social capital was significantly associated with perceived health (β = 0.20; P
< 0.001) and with emotional exhaustion (β = −0.34; P
< 0.001). Both the health indicators, in turn, were associated with absenteeism, presenteeism, and effective personal functioning in the presumed direction, that is, better health was associated with better functioning. Especially, bonding
social capital was significantly associated with health (β = 0.14; P
< 0.01) and with emotional exhaustion (β = −0.26; P
< 0.001). Linking
social capital was associated with emotional exhaustion as well (β = −0.09; P
Organizational social capital was found to be a resource for employees' health, with meaningful business implications.
