We keep supervisors out of the behavior-based safety process so
that when an employee sees a supervisor approaching him and asking
about unsafe behavior, there's a very different flavor than that of a
peer doing it as part of a behavior-based safety program, ... While the employee's approach as part of a behavior-based
safety program might be 'I saw you do this,' the supervisor has the
role of a coach, saying, 'I'm working with you until your behavior
changes.'
