The authors tested 3 hypotheses regarding supervisor support in the work pl
ace. The validation hypothesis predicts that when employees are supported b
y their coworkers and the larger organization, they also receive more suppo
rt from their supervisors. The positive affectivity hypothesis predicts tha
t employees with positive dispositions receive more supervisor support beca
use they are more socially oriented and likable. The moderation hypothesis
predicts a joint multiplicative effect between validation and positive affe
ctivity. An assessment of the hypotheses among a sample of 1,882 hospital e
mployees in Korea provided strong support for the validation and moderation
hypotheses.
