Safety Moment - Should we reward workers for not getting hurt?

Here's a question:  "How did we get to a place where we started thinking that we could reward workers for not getting hurt?"  There are many companies that have long-running safety incentive programs, often at great expense and effort of the organization.  How did this become an idea that we thought would make a difference? If we believe we can reward workers for not getting hurt, then we must believe that getting hurt is a monetary choice made be workers with full knowledge of the outcome. That is crazy talk - and yet very good and very smart companies have these programs. Who is right?  See what you think.
