The chain mediating model of job stress and organizational silence was constructed and tested. Results The scores of perceived organizational support,work stress,organizational silence and work prosperity in 361 medical workers were （41.17±8.10）,（27.34±9.38）,（35.55±8.94） and （45.84±9.36）points,respectively. The work prosperity of medical staff was positively correlated with perceived organizational support（r>0,P<0.05）,and negatively correlated with work stress and organizational silence（r<0,P<0.05）. The total indirect effect of perceived organizational support on work prosperity was 0.244. The specific mediating effects of work stress and organizational silence on work prosperity accounted for 24.00% and 10.61% respectively,and the chain mediating effect of the two accounted for 11.16%.
