iatrogenic jumps from the contractor to suing the general contractor and/or the premises owner. Yes, that's theoretically an option, but far more often than not, it isn't a viable one. You could sue them if they affirmatively did something to cause the worker's injury (and even that isn't always straightforward), but usually, that isn't what happened. Usually, the construction worker is injured by the negligence of his employer or coworker, and general contractors and premises owners generally don't owe a duty to ensure that their contractors (such as the injured workers' employer) perform their duties in a safe manner.
The only way you can get at a general contractor is if it retains a right of control over the details of the work performed by the injured person. Usually, they do have such control, so why don't these cases typically work? Because the nature of the control has to be very specific not just to what's going on on the job site but to the actual mechanism that caused the injury. Nevertheless, the real barrier is that there's an enormous mountain of Supreme Court and court of appeals decisions reviewing the evidence of control that typically exists and deeming it insufficient as a matter of law, which means the court is wiping its *** with your Seventh Amendment rights. You don't even get your day in court.
To say that an injured employee's option to sue a GC or owner is not a viable option is laughable. This happens regularly even if the injured employee is already collecting, or has already collected, workers comp benefits. In the event the injured employee's employer had comp, and the comp paid out, and if the employee wins the suit against the GC/owner, he gets to keep the amount remaining after the workers comp insurer is paid back- after his lawyer keeps 40% of the award. I'm guessing everyone has seen the advertisements of some lawyers (television, phone book covers, billboards) begging for injured employees to call them. The lawyers even come up with descriptive names like "The Hammer".
So why do these cases typically work in favor of the injured employee? First, because Supreme Court decisions are not involved ( a typical plaintiff lawyer is happy to argue a case even if the law is against him), and second, because legal fees charged by lawyers are extremely high. Most lawyers try and drag out a case as long as possible in order to keep up their billable hours, so the insurance carriers would rather just settle for "x" amount as opposed to being dragged through the courts for 3 or 4 years and running up ridiculous legal bills.
