That is so, Mr. Kramp. We don't know. These would have been employees of small independent contractors prior to 2004.
I must tell you, while I share your view that when you think about immediate safety you think about things that can kill you right away, I myself have had to learn about repetitive stress. We're not experts in that field. We've had to acquire expertise to help us understand it. We're still doing work in that area to let us come to some determination, as an employer, on how much repetitive stress you can absorb before you're put in a situation of risk.
I actually cannot give the honourable members of the committee an answer to that question today, but next time I appear, I will have more information on that.
