Can Laws Protect Whistle-Blowers?

Data collected over three time periods, from 1980 to 1992, show massive changes in the ways in which federal employees reported wrongdoing and the effects on them for having done so. Laws intended to encourage whistle-blowing seem to have two desired effects: to reduce the incidence of perceived wrongdoing and to increase the likelihood of whistle-blowing. However, two unintended effects are also observed: perceived retaliation increased and whistle-blowers increasingly sought anonymity. The basic model predicting retaliation is essentially the same in the three time periods in which data were collected. Implications for research, practice, and the design of future legislation are discussed.
