This article examines how the evaluation of disciplinary appeals in no
n-union organizations is affected by the use of procedural guidelines.
Data were collected from 142 managers in a simulation study designed
to assess the impact of procedures that are common within arbitration
and judicial systems but less common within non-union appeal systems.
Procedures which allowed decision makers to evaluate the reasonablenes
s of the disciplinary rule, which specified a stringent standard of pr
oof, and which restricted the availability of work history information
significantly increased the likelihood of affirmative responses to di
sciplinary appeals. It was also found that the effect of the standard
of proof guideline significantly increased when the evidence against t
he employee was weak. The implications of these findings for the desig
n of appeal systems and for future research are discussed.
