What I was trying to convince companies with the report is that if you're increasing productivity in the field, that has a pretty large impact on profitability. And there is still a need to improve productivity out there.

When you start motivating people to work faster, you've got to keep safety in there because you can work faster at the expense of safety.

Perhaps some people, for bad reasons, don't want to be monitored because they're not the most productive. Even good workers could take some offense to being monitored, as if maybe there is a lack of trust in what they're doing.

If anything, you should have an open system. There has to be a feeling of justness to this and the overall strategy.
