Zohar, 2002: Providing feedback to supervisors about subordinates' safety-related behavior improved workplace safety over five months
Reference:
Summary:
Providing supervisors in a regional maintenance center focused on heavy-duty equipment weekly feedback on the cumulative frequency of subordinates’ reports of safety-related conversations with supervisors over 8 weeks, as well as communications of the priority put on safety by superiors, increased the frequency of safety-related conversations reported by subordinates and improved workplace safety, including frequency of ear plug use from 25% to 73%, up to 5 months after the intervention ended as compared to a randomized control group. In addition, whereas the microaccident rate (minor injuries that occurred due to unsafe behavior during work hours) increased in the control group over a three-month assessment period, it declined in the treatment group.
