Mike, you dance around a very real issue, one that is not often appreciated:

Bad management results in not only disappointing results, but greatly increased expenses. Accidents are one of the greatest expenses.
Moreover, a firm that has nothing but contempt for it's people will see that attitude passed on to the customers.

For an example of the latter, here we have a few "Big Box" general retail chains. One stood head and shoulders over the rest as recently as the ;ate '70's.... and had nothing but contempt for those who actually were dumb enough to volunteer to become their employees / slaves. Naturally, the employees passsed their lack of enthusiasm on to the customers. Management was so focused on keeping the serfs on the manor that they failed to serve their customers, as well.
End result? A new chain, founded by one of their management "failures", sprang up and has since become the worlds' largest retailer. The original firm has been loitering around the bankruptcy courts.


Likewise, I have seen countless firms stumble along. Old equipment. Illegal labor. Unsafe practices -often caused by improper equipment and inadequate training- the norm. The end result has been lots of accidents and little profit.
Indeed, the result of one place having two serious accidents -the authorities can't help but react when limbs are lost- drove one place out of state. Another was shut down permanently when an explosion killed a few of their illegal workers.

The best you can do, at this point, is document the daylights out of your experiences.... and make damn sure there is a paper trail leading to the executive suite. Paper tends to take on a life of its' own, and will come back to haunt them if they fail to respond.
